Why do you need to override only CMAKE_C_FLAGS_RELEASE?
Overriding CMAKE_C_FLAGS_<CONFIG> directly is not possible AFAIK (where
<CONFIG> is determined by CMAKE_BUILD_TYPE).
Custom build flags are usually supplied using the CMAKE_C_FLAGS var. By
documentation this var specifies "flags used regardless of the value of
CMAKE_BUILD_TYPE".
The flags used for compilation are then e.g.:
"${CMAKE_C_FLAGS} ${CMAKE_C_FLAGS_RELEASE}"
So as it seems CMAKE_C_FLAGS is prepended rather than appended. This however is
cmake magic. Not sure if that's what you need.
