[CMake] Where does cmake look for include files?

[Marianne B. Wiese]

Hello

Just to let you know:

It turns out that the way cmake looks for a file to include, is by
TRY_CO)MPILE() a tiny c-file whith for example #include GL/glu.h.

However, Visual C++ cannot compile with #include <glu.h> if <windows.h> is
not included too.
Therefore I will not succeed in compiling FLTK, unless I change
checkincludefiles.cmake.

I think I will give it up, and see if I can get Orfeo Toolbox to work with a
binary installed FLTK instead.

Thanks for the answers.
