[CMake] initializing default values

[William A. Hoffman]

One way to do this is to create new cache variables.

# create a new variable and initialize it how you like and put it in
# the cache with no FORCE
SET(MYPROJ_CXX_FLAGS "...." CACHE STRING "common C++ build flags")
# Force the cmake variable to always have the value of your new variable
# Also change the type to INTERNAL so users can not edit it in ccmake or
# CMakeSetup.
SET(CMAKE_CXX_FLAGS "${MYPROJ_CXX_FLAGS}" CACHE INTERNAL "Internal flags do not edit" FORCE)
