When compiling mapmap_cpu as part of the bigger system, the compilation was failing, because instead of appending to CMAKE_CXX_FLAGS, this variable was being overwritten, so all the options for finding header files were being lost. This offers a fix. It should not change anything if this variable starts empty.
