# CMake configuration for Nana # Contributors: # Andrew Kornilov (ierofant) - original version # Jinhao # Ariel Vina-Rodriguez (qPCR4vir) # Robert Hauck - Enable support for PNG/Freetype # Pavel O. - fix compilation with boost::filesystem (#281) # Frostbane - Add option for compiling a shared library (#263,#265) # Qiangqiang Wu - Add biicode support # # Nana uses some build systems: MS-VS solution, MAKE, bakefile, codeblock, etc. manually optimized. # Maybe CMake will be used in the future to generate some of them in the central nana repository. # But by now CMake is just one option and all the other distributed build system # files/projects are manually writen. 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://cliutils.gitlab.io/modern-cmake/ # https://cmake.org/cmake-tutorial/ # https://cmake.org/cmake/help/v3.12/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. # https://bbs.archlinux.org/viewtopic.php?id=84967 cmake_minimum_required(VERSION 3.12) project(nana VERSION 1.6.2 DESCRIPTION "C++ GUI library" HOMEPAGE_URL http://nanapro.org LANGUAGES CXX ) option(BUILD_SHARED_LIBS "Compile nana as a shared library."
