cmake --help-command TARGET_LINK_LIBRARIES

will show you how to do this.  Basically you just specify a separate 
library for each:

TARGET_LINK_LIBRARIES(myexe ... debug third_debug optimized third_opt)

I do not think there is a cross-platform way to do this right now. 
However, "NDEBUG" is defined for all release builds and not defined for 
debug builds on all platforms.  You can use this in a header file to 
define/undefine whatever macros you want.
