[CMake] Macro Problem

[Ryan Pavlik]

By default, variables (such as CMAKE_C_FLAGS and CMAKE_CXX_FLAGS) open a new
nested scope with each subdirectory.  So, any changes you make in a
directory will only be seen in that directory and its children, not any
parent or sibling directories.

So, in short, you can just do what you were planning to do, it should work
fine.
