Summary0001790: GET_TARGET_PROPERTY OBJECT_FILES
DescriptionSeveral users have asked about linking lots of small libraries yet also providing a single big library with the same objects. Currently CMake cannot do this even though we support external object files. Now that local generate has been removed all runs of cmake have global knowledge and the configure stage can hook into the generators. This would allow us to provide this target property:

GET_TARGET_PROPERTY(SMALL_A_OBJS smallA OBJECT_FILES)
GET_TARGET_PROPERTY(SMALL_B_OBJS smallB OBJECT_FILES)

ADD_LIBRARY(big ${SMALL_A_OBJS} ${SMALL_B_OBJS})

It would be quite cool if this could somehow be made to work. It would make compiling KDE with cmake much easier :-)

Any progress on this ?
How about this idea: http://public.kitware.com/pipermail/cmake/2005-September/007291.html [^]

I think this can be considered fixed now in 2.8.8 based on the OBJECT library feature (see bottom of help text for add_library):

Please re-open and add a note to discuss if you disagree...
