Fix Windows CMake builds with shared zlib On Linux, if shared zlib is present, zlib.h is always available and -lz links to zlib, even if you don't run find_package(ZLIB). For some reason I have zlib installed on Windows (possibly from vcpkg), so find_package(ZLIB) succeeds and ZLIB_FOUND is true. When Dolphin uses shared zlib on Windows, the problem is that zlib.h is not in the default include path, and the CMake target is called ZLIB::ZLIB and there's neither a target nor a library called z. However, both find_package(ZLIB) and add_subdirectory(Externals/zlib) create a target called ZLIB::ZLIB, so I'll switch to that instead. Hopefully this change doesn't break anyone's build. 2020-06-05 21:01:16 +00:00			`target_link_libraries(png PUBLIC ZLIB::ZLIB)`
