c++ - CMake FIND_LIBRARY works on Windows but not OS X -

the same code ran on cmake in windows finds libraries, on mac cannot find them.the code finds include directories fine not libraries

here screen of cmake output

and here screen of directory construction

here cmakelists.txt

the proper filename extension libraries varies on different platforms. while .lib used both static , dll import libraries on windows, os x uses different naming conventions (.a static , .so/.dylib dynamic libraries, perchance lib prefix).

in order still allow code works different naming conventions, find_library expects omit extensions or prefixes , just give bare name of library.

so instead of find_library(sdl2 names sdl2.lib [...]) should write find_library(sdl2 names sdl2 [...]).

from question seems trying link os x build against windows binaries (.lib , .dll file extensions). this not work. need separate set of binaries compiled os x.
