I'm wondering how I would go about adding an include directory to the system search path for a CMake project. Particularly, I've some source that I'm trying to build a CMake project for.
The source is not mine, and so I don't really want to modify it.
The source has the following include directive:
#include <foo/bar.h>
So I need to add the directory containing foo to my search path. Is this something I can set within the CMakeLists.txt?
