Here's another suggestion. The Learn Open GL (logl) repository includes windows specific pre-compiled libraries. To make sure that the windows library can't be found, rename the file 'freetype.lib' in the 'lib' folder to something like 'dontusefreetype.lib'. The linker then should only find the freetype library installed in the system.
Please give this a try and report back, and please include any relevant error messages.
Thanks.

the solution to this problem.
It works.

What did you do after edit the CMakeLists.text file?

I tried to do the following commands one more time:

cmake ../.
make -j8

But nothing change, it doesn't work!

like the diff above, you should

  1. add FIND_PACKAGE(Freetype REQUIRED)
  2. change SET(APPLE_LIBS ${APPLE_LIBS} ${GLFW3_LIBRARY} ${ASSIMP_LIBRARY} ${FREETYPE_LIBRARIES})

then, you can compile it successfully with

cmake ../.
make -j8

I just lost the FIND_PACKAGE(Freetype REQUIRED)
and need to run brew install freetype
