0027053: Compilation fails with "fatal error RC1103: invalid option, /fp:precise"

Browse Source 
CMake script is corrected to add compiler options (except macro definitions) to CMAKE_CXX_FLAGS and CMAKE_C_FLAGS variables directly, instead of using add_definitions() command.
This eliminates failure of build by NMake due to incorrect options passed to RC compiler.
