[Cmake] space-separated compiler flags, cmake command line

[Wheeler, Fred (Research)]

When I pass options like these to cmake

  -DCMAKE_C_FLAGS:STRING="-02 -Wall -fprofile-arcs -ftest-coverage"
  -DCMAKE_CXX_FLAGS:STRING="-O2 -Wall -fprofile-arcs -ftest-coverage"

I get escaped spaces in the cache file and makefiles,

% grep test-coverage *
[...]
CMakeCache.txt:CMAKE_CXX_FLAGS:STRING=-O2\ -Wall\ -fprofile-arcs\ -ftest-coverage
CMakeCache.txt:CMAKE_C_FLAGS:STRING=-02\ -Wall\ -fprofile-arcs\ -ftest-coverage
Makefile:CMAKE_C_FLAGS       = -02\ -Wall\ -fprofile-arcs\ -ftest-coverage
Makefile:CMAKE_CXX_FLAGS     = -O2\ -Wall\ -fprofile-arcs\ -ftest-coverage
[...]

Is there a way to pass a set of space-separated compiler flags to cmake via the command line?

Thanks,
Fred Wheeler
