Fixed bug 2464 - Configure a sdl2-config.cmake.in together with sdl2.pc.in Leonardo Despite having a CMakeLists.txt file, SDL2 seems to be mainly built using the autotools system by package-managers. It is nice to have it but it is only useful if you are building SDL2 by yourself. People that want to use CMake to find their already-installed SDL2 are using a FindSDL2.cmake module based on the old FindSDL.cmake. This is not deprecated but it is discouraged by the CMake devs (see http://www.cmake.org/Bug/view.php?id=14826), as these modules needs maintainers to be included in the official CMake installation. To fix that, SDL and its accompanying libraries could configure a simple sdl2-config.cmake file, much like it does with sdl2.pc.in. We don't need to configure a full sdl2-config.cmake as in this post, http://forums.libsdl.org/viewtopic.php?t=10068&sid=ccf8abbf0d73fb03ae9cded991e60959 (because it depends on it being built with CMake). Using something as simple as http://www.cmake.org/Wiki/CMake/Tutorials/Packaging#Package_Configuration_Files is deemed enough. Here is another: http://quickgit.kde.org/?p=prison.git&a=blob&f=lib%2Fprison%2FPrisonConfig.cmake.in

Fixed typo in sdl2-config.cmake.in (thanks, Rafal!). Partially fixes Bugzilla #3208.

build: Merge pkg-config Libs.private into Libs for static-only builds A project being built entirely statically will call pkg-config with --static, which utilises the Libs.private field. Conversely it will not use --static when not being built entirely statically, even if there is only a static build of SDL available. This will most likely cause the build to fail due to underlinking unless we merge the Libs fields. This is what the Meson build system does when it generates pkg-config files. This also also follows the behaviour of sdl2-config. At the same time, the runtime linker flags are not applicable to static-only builds so only add them for shared builds.
