add CMake config file that follows CMake conventions #545

Open bebuch opened 6 months ago

bebuch commented 6 months ago

New functionality:

add a CMake config file to the install, so an installed libpng can be found via find_package(libpng)
mark API header includes as SYSTEM headers in install, so warnings in these headers can be disabled

Changed behavior:

export the target libpng as libpng::libpng which follows the CMake convention for exported targets (previous it was just libpng)
install CMake files to lib/cmake/libpng instead of lib/libpng to follow the CMake convention

I have now changed the PR so that it creates the config files I wanted and does not touch anything else. Ready to merge from my side! 😸

@ctruta If you find some time to work on libpng, it would be nice if you could merge this. That way we can use 1.6.44 without a patch once that is tagged. 🙂

@ctruta Since I just saw that you are active again, it would be nice if you could merge this ;-)
