Matthias Schiffer	fdce587c74	build: update to modern CMake, use pkg-config for zlib and libpng ... Starting with CMake 3.7, we can avoid dealing with individual variables for include dirs, libraries, ... for dependencies found using pkg-config, and instead just reference them using an imported target.	2021-08-24 13:14:48 +02:00
