@ -11,3 +11,7 @@ NOTE: for compilation with MinGW, fnmatch.h is probably missing.
That file can be found here:
http://www.koders.com/c/fid2B518462CB1EED3D4E31E271DB83CD1582F6EEBE.aspx
It should be installed in the mingw include directory.
NOTE: for the OpenGL engine on Windows, the glew library:
http://glew.sourceforge.net/
is needed.
