CMakeLists.txt

# This is an demonstration cmake build file for ripple-libpp
#
# cmake support in ripple-libpp. Currently supports:
#
#  * debug/release
#  * sanitizer builds
#  * optional release build with assert turned on
#  * `target` variable to easily set compiler/debug
#     (i.e. -Dtarget=gcc.debug)
#  * gcc/clang/visual studio/xcode
#  * linux/mac/win
#  * gcc 4 ABI, when needed
#  * ninja builds
#  * check openssl version on linux
#  * static builds (swd TBD: needs to be tested by building & deploying on different systems)
#
# TBD:
#  * jemalloc support
#  * count
#
# Notes:
#  * Use the -G"Visual Studio 14 2015 Win64" generator on Windows. Without this
#    a 32-bit project will be created. There is no way to set the generator or
#    force a 64-bit build in CMakeLists.txt (setting CMAKE_GENERATOR_PLATFORM won't work).
#    The best solution may be to wrap cmake with a script.
#
#  * It is not possible to generate a visual studio project on linux or
#    mac. The visual studio generator is only available on windows.
#
#  * Language is _much_ worse than python, poor documentation and "quirky"
#    language support (for example, generator expressions can only be used
#    in limited contexts and seem to work differently based on
#    context (set_property can set multiple values, add_compile_options
#    can not/or is buggy)
#
#  * Could not call out to `sed` because cmake messed with the regular
#    expression before calling the external command. I did not see a way
#    around this.
#
#  * Makefile generators want to be single target. It wants a separate
#    directory for each target type. I saw some mentions on the web for
#    ways around this bug haven't look into it. The visual studio project
#    does support debug/release configurations in the same project (but
#    not unity/non-unity).
