It also sets the + ``_FOUND`` variable. The package is considered found if all + variables listed contain valid results, e.g. valid filepaths. + + There are two signatures: + + .. code-block:: cmake + + find_package_handle_standard_args( + (DEFAULT_MSG|) + ... + ) + + find_package_handle_standard_args( + [FOUND_VAR ] + [REQUIRED_VARS ...] + [VERSION_VAR ] + [HANDLE_VERSION_RANGE] + [HANDLE_COMPONENTS] + [CONFIG_MODE] + [NAME_MISMATCHED] + [REASON_FAILURE_MESSAGE ] + [FAIL_MESSAGE ] + ) + + The ``_FOUND`` variable will be set to ``TRUE`` if all + the variables ``...`` are valid and any optional + constraints are satisfied, and ``FALSE`` otherwise. A success or + failure message may be displayed based on the results and on + whether the ``REQUIRED`` and/or ``QUIET`` option was given to + the :command:`find_package` call. + + The options are: + + ``(DEFAULT_MSG|)`` + In the simple signature this specifies the failure message. + Use ``DEFAULT_MSG`` to ask for a default message to be computed + (recommended). Not valid in the full signature. + + ``FOUND_VAR `` + .. deprecated:: 3.3 + + Specifies either ``_FOUND`` or + ``_FOUND`` as the result variable. This exists only + for compatibility with older versions of CMake and is now ignored. + Result variables of both names are always set for compatibility. + + ``REQUIRED_VARS ...`` + Specify the variables which are required for this package. + These may be named in the generated failure message asking the + user to set the missing variable values. Therefore these should + typically be cache entries such as ``FOO_LIBRARY`` and not output + variables like ``FOO_LIBRARIES``. + + .. versionchanged:: 3.18 + If ``HANDLE_COMPONENTS`` is specified, this option can be omitted. + + ``VERSION_VAR `` + Specify the name of a variable that holds the version of the package + that has been found. This version will be checked against the + (potentially) specified required version given to the + :command:`find_package` call, including its ``EXACT`` option. + The default messages include information about the required + version and the version which has been actually found, both + if the version is ok or not. + + ``HANDLE_VERSION_RANGE`` + .. versionadded:: 3.19 + + Enable handling of a version range, if one is specified. Without this + option, a developer warning will be displayed if a version range is + specified. + + ``HANDLE_COMPONENTS`` + Enable handling of package components. In this case, the command + will report which components have been found and which are missing, + and the ``_FOUND`` variable will be set to ``FALSE`` + if any of the required components (i.e. not the ones listed after + the ``OPTIONAL_COMPONENTS`` option of :command:`find_package`) are + missing. + + ``CONFIG_MODE`` + Specify that the calling find module is a wrapper around a + call to ``find_package( NO_MODULE)``. This implies + a ``VERSION_VAR`` value of ``_VERSION``. The command + will automatically check whether the package configuration file + was found. + + ``REASON_FAILURE_MESSAGE `` + .. versionadded:: 3.16 + + Specify a custom message of the reason for the failure which will be + appended to the default generated message. + + ``FAIL_MESSAGE `` + Specify a custom failure message instead of using the default + generated message. Not recommended. + + ``NAME_MISMATCHED`` + .. versionadded:: 3.17 + + Indicate that the ```` does not match + ``${CMAKE_FIND_PACKAGE_NAME}``. This is usually a mistake and raises a + warning, but it may be intentional for usage of the command for components + of a larger package. + +Example for the simple signature: + +.. code-block:: cmake + + find_package_handle_standard_args(LibXml2 DEFAULT_MSG + LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR) + +The ``LibXml2`` package is considered to be found if both +``LIBXML2_LIBRARY`` and ``LIBXML2_INCLUDE_DIR`` are valid. +Then also ``LibXml2_FOUND`` is set to ``TRUE``. If it is not found +and ``REQUIRED`` was used, it fails with a +:command:`message(FATAL_ERROR)`, independent whether ``QUIET`` was +used or not. If it is found, success will be reported, including +the content of the first ````. On repeated CMake runs, +the same message will not be printed again. + +.. note:: + + If ```` does not match ``CMAKE_FIND_PACKAGE_NAME`` for the + calling module, a warning that there is a mismatch is given. The + ``FPHSA_NAME_MISMATCHED`` variable may be set to bypass the warning if using + the old signature and the ``NAME_MISMATCHED`` argument using the new + signature. To avoid forcing the caller to require newer versions of CMake for + usage, the variable's value will be used if defined when the + ``NAME_MISMATCHED`` argument is not passed for the new signature (but using + both is an error).. + +Example for the full signature: + +.. code-block:: cmake + + find_package_handle_standard_args(LibArchive + REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR + VERSION_VAR LibArchive_VERSION) + +In this case, the ``LibArchive`` package is considered to be found if +both ``LibArchive_LIBRARY`` and ``LibArchive_INCLUDE_DIR`` are valid. +Also the version of ``LibArchive`` will be checked by using the version +contained in ``LibArchive_VERSION``. Since no ``FAIL_MESSAGE`` is given, +the default messages will be printed. + +Another example for the full signature: + +.. code-block:: cmake + + find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4) + find_package_handle_standard_args(Automoc4 CONFIG_MODE) + +In this case, a ``FindAutmoc4.cmake`` module wraps a call to +``find_package(Automoc4 NO_MODULE)`` and adds an additional search +directory for ``automoc4``. Then the call to +``find_package_handle_standard_args`` produces a proper success/failure +message. + +.. command:: find_package_check_version + + .. versionadded:: 3.19 + + Helper function which can be used to check if a ```` is valid + against version-related arguments of :command:`find_package`. + + .. code-block:: cmake + + find_package_check_version( + [HANDLE_VERSION_RANGE] + [RESULT_MESSAGE_VARIABLE ] + ) + + The ```` will hold a boolean value giving the result of the check. + + The options are: + + ``HANDLE_VERSION_RANGE`` + Enable handling of a version range, if one is specified.

On repeated CMake runs, -the same message will not be printed again. - -.. note:: - - If ```` does not match ``CMAKE_FIND_PACKAGE_NAME`` for the - calling module, a warning that there is a mismatch is given. The - ``FPHSA_NAME_MISMATCHED`` variable may be set to bypass the warning if using - the old signature and the ``NAME_MISMATCHED`` argument using the new - signature. To avoid forcing the caller to require newer versions of CMake for - usage, the variable's value will be used if defined when the - ``NAME_MISMATCHED`` argument is not passed for the new signature (but using - both is an error).. - -Example for the full signature: - -.. code-block:: cmake - - find_package_handle_standard_args(LibArchive - REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR - VERSION_VAR LibArchive_VERSION) - -In this case, the ``LibArchive`` package is considered to be found if -both ``LibArchive_LIBRARY`` and ``LibArchive_INCLUDE_DIR`` are valid. -Also the version of ``LibArchive`` will be checked by using the version -contained in ``LibArchive_VERSION``. Since no ``FAIL_MESSAGE`` is given, -the default messages will be printed. - -Another example for the full signature: - -.. code-block:: cmake - - find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4) - find_package_handle_standard_args(Automoc4 CONFIG_MODE) - -In this case, a ``FindAutmoc4.cmake`` module wraps a call to -``find_package(Automoc4 NO_MODULE)`` and adds an additional search -directory for ``automoc4``. Then the call to -``find_package_handle_standard_args`` produces a proper success/failure -message. - -.. command:: find_package_check_version - - .. versionadded:: 3.19 - - Helper function which can be used to check if a ```` is valid - against version-related arguments of :command:`find_package`. - - .. code-block:: cmake - - find_package_check_version( - [HANDLE_VERSION_RANGE] - [RESULT_MESSAGE_VARIABLE ] - ) - - The ```` will hold a boolean value giving the result of the check. - - The options are: - - ``HANDLE_VERSION_RANGE`` - Enable handling of a version range, if one is specified.

Moreover, ``debug`` versions will be - searched **after** ``non-debug`` ones. - - For example, if we have:: - - set (Python3_FIND_ABI "ON" "ANY" "ANY") - - The following flags combinations will be appended, in that order, to the - artifact names: ``dmu``, ``dm``, ``du``, and ``d``. - - And to search any possible ABIs:: - - set (Python3_FIND_ABI "ANY" "ANY" "ANY") - - The following combinations, in that order, will be used: ``mu``, ``m``, - ``u``, ````, ``dmu``, ``dm``, ``du`` and ``d``. - - .. note:: - - This hint is useful only on ``POSIX`` systems. So, on ``Windows`` systems, - when ``Python3_FIND_ABI`` is defined, ``Python`` distributions from - `python.org `_ will be found only if value for - each flag is ``OFF`` or ``ANY``. - -``Python3_FIND_STRATEGY`` - .. versionadded:: 3.15 - - This variable defines how lookup will be done. - The ``Python3_FIND_STRATEGY`` variable can be set to one of the following: - - * ``VERSION``: Try to find the most recent version in all specified - locations. - This is the default if policy :policy:`CMP0094` is undefined or set to - ``OLD``. - * ``LOCATION``: Stops lookup as soon as a version satisfying version - constraints is founded. - This is the default if policy :policy:`CMP0094` is set to ``NEW``. - -``Python3_FIND_REGISTRY`` - .. versionadded:: 3.13 - - On Windows the ``Python3_FIND_REGISTRY`` variable determine the order - of preference between registry and environment variables. - The ``Python3_FIND_REGISTRY`` variable can be set to one of the following: - - * ``FIRST``: Try to use registry before environment variables. - This is the default. - * ``LAST``: Try to use registry after environment variables. - * ``NEVER``: Never try to use registry. - -``Python3_FIND_FRAMEWORK`` - .. versionadded:: 3.15 - - On macOS the ``Python3_FIND_FRAMEWORK`` variable determine the order of - preference between Apple-style and unix-style package components. - This variable can take same values as :variable:`CMAKE_FIND_FRAMEWORK` - variable. - - .. note:: - - Value ``ONLY`` is not supported so ``FIRST`` will be used instead. - - If ``Python3_FIND_FRAMEWORK`` is not defined, :variable:`CMAKE_FIND_FRAMEWORK` - variable will be used, if any. - -``Python3_FIND_VIRTUALENV`` - .. versionadded:: 3.15 - - This variable defines the handling of virtual environments managed by - ``virtualenv`` or ``conda``. It is meaningful only when a virtual environment - is active (i.e. the ``activate`` script has been evaluated). In this case, it - takes precedence over ``Python3_FIND_REGISTRY`` and ``CMAKE_FIND_FRAMEWORK`` - variables. The ``Python3_FIND_VIRTUALENV`` variable can be set to one of the - following: - - * ``FIRST``: The virtual environment is used before any other standard - paths to look-up for the interpreter. This is the default. - * ``ONLY``: Only the virtual environment is used to look-up for the - interpreter. - * ``STANDARD``: The virtual environment is not used to look-up for the - interpreter but environment variable ``PATH`` is always considered. - In this case, variable ``Python3_FIND_REGISTRY`` (Windows) or - ``CMAKE_FIND_FRAMEWORK`` (macOS) can be set with value ``LAST`` or - ``NEVER`` to select preferably the interpreter from the virtual - environment. - - .. versionadded:: 3.17 - Added support for ``conda`` environments. - - .. note:: - - If the component ``Development`` is requested, it is **strongly** - recommended to also include the component ``Interpreter`` to get expected - result. - -``Python3_FIND_IMPLEMENTATIONS`` - .. versionadded:: 3.18 - - This variable defines, in an ordered list, the different implementations - which will be searched. The ``Python3_FIND_IMPLEMENTATIONS`` variable can - hold the following values: - - * ``CPython``: this is the standard implementation. Various products, like - ``Anaconda`` or ``ActivePython``, rely on this implementation. - * ``IronPython``: This implementation use the ``CSharp`` language for - ``.NET Framework`` on top of the `Dynamic Language Runtime` (``DLR``). - See `IronPython `_. - * ``PyPy``: This implementation use ``RPython`` language and - ``RPython translation toolchain`` to produce the python interpreter. - See `PyPy `_. - - The default value is: - - * Windows platform: ``CPython``, ``IronPython`` - * Other platforms: ``CPython`` - - .. note:: - - This hint has the lowest priority of all hints, so even if, for example, - you specify ``IronPython`` first and ``CPython`` in second, a python - product based on ``CPython`` can be selected because, for example with - ``Python3_FIND_STRATEGY=LOCATION``, each location will be search first for - ``IronPython`` and second for ``CPython``. - - .. note:: - - When ``IronPython`` is specified, on platforms other than ``Windows``, the - ``.Net`` interpreter (i.e. ``mono`` command) is expected to be available - through the ``PATH`` variable. - -``Python3_FIND_UNVERSIONED_NAMES`` - .. versionadded:: 3.20 - - This variable defines how the generic names will be searched. Currently, it - only applies to the generic names of the interpreter, namely, ``python3`` and - ``python``. - The ``Python3_FIND_UNVERSIONED_NAMES`` variable can be set to one of the - following values: - - * ``FIRST``: The generic names are searched before the more specialized ones - (such as ``python3.5`` for example). - * ``LAST``: The generic names are searched after the more specialized ones. - This is the default. - * ``NEVER``: The generic name are not searched at all. - -Artifacts Specification -^^^^^^^^^^^^^^^^^^^^^^^ - -.. versionadded:: 3.16 - -To solve special cases, it is possible to specify directly the artifacts by -setting the following variables: - -``Python3_EXECUTABLE`` - The path to the interpreter. - -``Python3_COMPILER`` - The path to the compiler. - -``Python3_DOTNET_LAUNCHER`` - .. versionadded:: 3.18 - - The ``.Net`` interpreter. Only used by ``IronPython`` implementation. - -``Python3_LIBRARY`` - The path to the library. It will be used to compute the - variables ``Python3_LIBRARIES``, ``Python3_LIBRARY_DIRS`` and - ``Python3_RUNTIME_LIBRARY_DIRS``. - -``Python3_INCLUDE_DIR`` - The path to the directory of the ``Python`` headers. It will be used to - compute the variable ``Python3_INCLUDE_DIRS``. - -``Python3_NumPy_INCLUDE_DIR`` - The path to the directory of the ``NumPy`` headers. It will be used to - compute the variable ``Python3_NumPy_INCLUDE_DIRS``. - -.. note:: - - All paths must be absolute. Any artifact specified with a relative path - will be ignored. - -.. note:: - - When an artifact is specified, all ``HINTS`` will be ignored and no search - will be performed for this artifact. - - If more than one artifact is specified, it is the user's responsibility to - ensure the consistency of the various artifacts. - -By default, this module supports multiple calls in different directories of a -project with different version/component requirements while providing correct -and consistent results for each call. To support this behavior, ``CMake`` cache -is not used in the traditional way which can be problematic for interactive -specification. So, to enable also interactive specification, module behavior -can be controlled with the following variable: - -``Python3_ARTIFACTS_INTERACTIVE`` - .. versionadded:: 3.18 - - Selects the behavior of the module. This is a boolean variable: - - * If set to ``TRUE``: Create CMake cache entries for the above artifact - specification variables so that users can edit them interactively. - This disables support for multiple version/component requirements. - * If set to ``FALSE`` or undefined: Enable multiple version/component - requirements. - -Commands -^^^^^^^^ - -This module defines the command ``Python3_add_library`` (when -:prop_gbl:`CMAKE_ROLE` is ``PROJECT``), which has the same semantics as -:command:`add_library` and adds a dependency to target ``Python3::Python`` or, -when library type is ``MODULE``, to target ``Python3::Module`` and takes care -of Python module naming rules:: - - Python3_add_library ( [STATIC | SHARED | MODULE [WITH_SOABI]] - [ ...]) - -If the library type is not specified, ``MODULE`` is assumed. - -.. versionadded:: 3.17 - For ``MODULE`` library type, if option ``WITH_SOABI`` is specified, the - module suffix will include the ``Python3_SOABI`` value, if any. -#]=======================================================================] - - -set (_PYTHON_PREFIX Python3) - -set (_Python3_REQUIRED_VERSION_MAJOR 3) - -include (${CMAKE_CURRENT_LIST_DIR}/FindPython/Support.cmake) - -if (COMMAND __Python3_add_library) - macro (Python3_add_library) - __Python3_add_library (Python3 ${ARGV}) - endmacro() -endif() - -unset (_PYTHON_PREFIX) From a12b09ae77c72dd8c19cce76ca915b1cbdf581e5 Mon Sep 17 00:00:00 2001 From: artivis Date: Fri, 9 Jul 2021 19:23:40 -0400 Subject: [PATCH 13/17] review python bindings install --- CMakeLists.txt | 7 ----- python/CMakeLists.txt | 52 ++++++++++++++++++++------------------ setup.py | 1 - test/python/CMakeLists.txt | 2 +- 4 files changed, 29 insertions(+), 33 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 63e6e060..e9ed4a38 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -61,15 +61,8 @@ option(BUILD_PYTHON_BINDINGS "Build Python bindings with pybind11."
