Dmitrijs Ledkovs, a package maintainer for 'blender' in Ubuntu,
proposed a solution for the build failure of Debian/Ubuntu package:
The solution uses pkg-config to find the include directories.
I'm not sure if this way can be used for all X11 systems, but it might
be helpful for fixing the problem.
