Where does the CLion IDE look for header files?

Question

I'm using the CLion IDE and need to put some OpenGL files in. In the JetBrains/CLion folder there's a bin and lib folder. In the lib folder theres jar files, do I put the header and dlls in here?

get this error:

CMakeFiles\GL.dir/objects.a(main.cpp.obj): In function `glutInit_ATEXIT_HACK':
c:/mingw/include/gl/glut.h:486: undefined reference to `__glutInitWithExit'

(1) you add include paths in [CMakeLists.txt](http://www.cmake.org/documentation/) (2) You should use system OpenGL headers — Ivan Aksamentov - Drop, Mar 03 '15 at 01:07
(3) It was bad idea to put `glut` headers inside `mingw` include folder. (4) Now you should link glut `.lib`(`.a`) to your program (with CMake) — Ivan Aksamentov - Drop, Mar 03 '15 at 01:32

From the FAQ here:

At present CLion supports GCC and Clang compilers and is guided by these two to get the libraries and headers paths.

So it depends on the compiler CLion is using where it looks for the header files.

CLion uses CMake as a build system, which in turn points out paths for any supported compiler – Ivan Aksamentov - Drop Mar 03 '15 at 01:10
It's not finding it. i put the GL section in MiniGW/include – Joe Mar 03 '15 at 01:28
@emlai I've installed both `Clang` and `GCC` in my MacOS, how can I find which one is it using? – asn Jan 05 '19 at 15:43
