Use relative paths (May not work!).
If this is set to TRUE, then the CMake will use relative paths between
the source and binary tree. This option does not work for more
complicated projects, and relative paths are used when possible. In
general, it is not possible to move CMake generated makefiles to a
different location regardless of the value of this variable.

This looks like asking for trouble. Why are you doing this?
