[CMake] Strange results from modifying CMAKE_CXX_FLAGS

[j.trauntvein at comcast.net]

I have been playing with modifying the CMAKE_CXX_FLAGS variable using the following SET command:

  SET(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} -symbolic)

The result of this as seen in the Makefile is that the -symbolic option is included but is preceded by a semi-colon which completely messes up g++.  Is my approach wrong?  My version of cmake is 2.0.6.
