You need to clean up your CMAKE_CXX_FLAGS and so forth so they are set 
in 1 user controllable place.

Not for profiling.  Not for optimization either, other than "Release" 
giving you sane defaults.  Nothing for CPU architecture specification 
either.

Do you actually need to profile on all platforms, or is this
