[CMake] flags for shared/static lib

[Totte Karlsson]

Hi,
I have a CMakeLists.txt that creates both a shared and static lib.
In short it looks something like this:

add_definitions(-DEXPORT_RR)
add_library(${target} 		SHARED ${rrSources})
add_library(${target}-static 	STATIC ${rrSources})


The problem being that for the static version, the flag
-DRR_STATIC should be defined.

How can one achieve that?
