[CMake] simple cmake example

[Tim Coddington]

Thank you.  After adapting your file ccmake complains about line 7:

  include(${MRPT_USE_FILE})

"CMake Error at CMakeLists.txt:7 (include):
   include called with wrong number of arguments.  Include only takes
one file."

How is MRPT_USE_FILE defined?

Thanks
