Yes, but the way you do that is you set environment variables.  Here is why.
FindSWIG.cmake is an official find modules that comes with CMake, and like
most such modules, it uses the fundamental CMake find commands (find_path,
find_program, find_library) which in turn (according to the extensive
documentation of these find commands) depends on environment variables to
find things that are in non-standard locations.

I am virtually positive it is standard on Linux with CMake, but I am not
sure for the Mac OS X platform.  CMake on Mac OS X probably follows whatever
policy Apple has about standard or non-standard /usr/local.

Another possibility is /usr/local is standard on Mac OS X, but swig is not
completely installed (or not correctly installed) on your platform. To check
that go through FindSWIG.cmake to see what files are being looked for and
check that you have them all.  If all are present then set PATH and
CMAKE_INCLUDE_PATH appropriately so they will be found, and that should
solve this issue.
