# CMake configuration for Nana
# Author: Andrew Kornilov(https://github.com/ierofant)
# Contributors:
# Jinhao
# Robert Hauck - Enable support for PNG/Freetype
# Qiangqiang Wu - Add biicode support
# Ariel Vina-Rodriguez (qPCR4vir)
# Pavel O. - fix compilation with boost::filesystem (#281)
# Frostbane - Add option for compiling a shared library (#263,#265)
#
# Nana uses some build systems: MS-VS solution, MAKE, bakefile, codeblock, etc. manually optimized.
# In the future CMake could be the prefered, and maybe will be used to generate the others and the central nana repo
# will distribute all of them. But by now CMake is just one of them and all the other distributed build system
# files/projects are manually write. This current CMakeList.txt reflect this fact and that is why we don't
# generate here configurated *.h files or explicitly enumerate the sources files: anyway this CM-list
# will be "touched" to force a re-run of cmake.
#https://cmake.org/cmake-tutorial/
#https://cmake.org/cmake/help/v3.3/module/CMakeDependentOption.html?highlight=cmakedependentoption
# use CACHE FORCE or set(ENABLE_MINGW_STD_THREADS_WITH_MEGANZ ON) or delete CMakecache.txt or the entirely build dir
# if your changes don't execute
# It seems that project() defines essential system variables like CMAKE_FIND_LIBRARY_PREFIXES.

# The library maybe available in the std library in use or from Boost (almost compatible)
# http://www.boost.org/doc/libs/1_60_0/libs/filesystem/doc/index.htm

# If you include the file <nana/filesystem/filesystem.hpp> or <nana/filesystem/filesystem_ext.hpp>
# the selected option will be set by nana into std::experimental::filesystem
# By default Nana will try to use the STD. If STD is not available and NANA_CMAKE_FIND_BOOST_FILESYSTEM
# is set to ON nana will try to use boost if available. Nana own implementation will be use if none of
# the previus were selected or available.
