Look at SET_TARGET_PROPERTIES
         i.e. the COMPILE_FLAGS

for example
ADD_EXECUTABLE(first source1.cpp source2.cpp)
SET_TARGET_PROPERTIES(first PROPERTIES
                                            COMPILE_FLAGS "-D_FIRST")

ADD_EXECUTABLE(second source1.cpp source2.cpp)
SET_TARGET_PROPERTIES(second PROPERTIES
                                            COMPILE_FLAGS "-D_SECOND")

should be OK.

SET_SOURCE_FILES_PROPERTIES may be useful too
if the compile flags may be attached to the source and not
to the target. This is not the case you described but I found
it usefull too.
