[Gmsh] compilation error

[Martijn Brouwer]

I have opencascade installed, with tons of header files
in /usr/include/opencascade. If I toggle the advanced settings on I see
that ccmake is able to find it: OCC_INC=/usr/include/opencascade.
Running ccmake DCMAKE_PREFIX_PATH=/usr/include/opencascade . does not
make any difference (as expected).
My opencascade installation does not have a config.h file.
I'll try the cvs snapshot.

Thanks for your help.
