[CMake] Mix Debug and Release Flags In One Library

[Jack Morrison]

I've overcome this by using the COMPILE_FLAGS source file property
http://www.cmake.org/cmake/help/v2.8.11/cmake.html#prop_sf:COMPILE_FLAGS

Those flags will be appended to the rest of the compiler flags, so you can
make them override the debug flags. For instance, if your debug flags are
"-UNDEBUG -DDEBUG -O1", you can set the COMPILE_FLAGS to "-DNDEBUG -UDEBUG
-O3" and (in my experience with GCC and Clang) the compiler will prefer the
latter flags.

Cheers,
Jack
