${COMPILE_DEFINITIONS_RELEASE} does not expand the property but you 
could use set_property() with the APPEND flag for that.

NDEBUG is set by default for MinSizeRel, Release and RelWithDebInfo so 
you should have found it in the Release flags even without using the 
property (unless you override the default flags).

With
   set_directory_properties(PROPERTIES COMPILE_DEFINITIONS_RELEASE "FOOBAR")

I get
   ./CMakeFiles/foo.dir/flags.make:CXX_DEFINES = -DFOOBAR
When configuring a Release build with the Makefiles generator.
