[CMake] include header files from external library

[Andy Lego]

Hi Leila,

When doing the search for the header files, specify the relative path within
the tree and not the actual header file. For example,

find_path(OPEN_MESH_INCLUDES
NAMES OpenMesh/balh/balh/something.h
)

instead of

find_path(OPEN_MESH_INCLUDES
NAMES something.h)

Then OPEN_MESH_INCLUDES will contain the toplevel dir.
