Documentation / Example needed for find_program

[mizvekov]

So, currently, installing tools with vcpkg and then trying to find them with 'find_program' isn't as straightforward as on traditional unix packaging systems.

For example, installing 'glslang' package on a typical system would put wherever 'glslangValidator' is in 'PATH', and then 'find_program(glsval glslangValidator)' would work with no additional setup.

Not so with vcpkg as far as I could find out.

The examples here are all about using libraries, not tools, so that is a problem as well.

It seems be not only a documentation issue but a issue on vcpkg tweaks for cmake, that is good for find_package but not enough for find_program.

Here is a tweak for cmake, https://github.com/Microsoft/vcpkg/blob/master/scripts/buildsystems/vcpkg.cmake

It defines CMAKE_PREFIX_PATH, CMAKE_FIND_ROOT_PATH, and CMAKE_FIND_ROOT_PATH for find_package to find vcpkg ports.
Also for find_program

list(APPEND CMAKE_PROGRAM_PATH ${_VCPKG_INSTALLED_DIR}/${VCPKG_TARGET_TRIPLET}/tools)
file(GLOB _VCPKG_TOOLS_DIRS ${_VCPKG_INSTALLED_DIR}/${VCPKG_TARGET_TRIPLET}/tools/*)
foreach(_VCPKG_TOOLS_DIR ${_VCPKG_TOOLS_DIRS})
    if(IS_DIRECTORY ${_VCPKG_TOOLS_DIR})
        list(APPEND CMAKE_PROGRAM_PATH ${_VCPKG_TOOLS_DIR})
    endif()
endforeach()

It looks fine.
