These look like *linker* errors, not *compiler* errors.


1) OpenGL binaries (DLLs) are installed as part of Windows itself, 
according to this:

http://www.opengl.org/about/overview/#5


2) The opengl header files come with the mingw g++ compliler. I see 
this file here:

C:\msys\1.0\mingw\include\GL\gl.h

which describes the entry points into the DLLs that should come with 
windows per 1) above.


3) On my system I see at least this DLL which seems to be in a system 
directory on Win2K:

C:\WINNT\system32\opengl.dll

---------------------

So you do not need to install glee.h.

If your build environment on windows was making the Kicad binaries using 
the old makefile.g95, then this says that you have all the opengl stuff 
already.

You are seeing a linker error, not a compile error. To trouble shoot 
that you need to see the linker command line. In order to see the 
linker command line, you need to build your makefiles using cmake using 
the "verbose" option

cmake -DCMAKE_VERBOSE_MAKEFILE=1 -DCMAKE_BUILD_TYPE=Release ../

This will expose the command line used to link your kicad binaries when 
you then later run make.

It seems that the linking step is not finding your opengl.dll
