I believe this will cause the doxygen target to be run every time, which
is not what the OP wants.

My first guess would be the ALL_TARGETS approach. Just make it part of
your coding standard that each time you do an
add_library/add_executable/add_custom_target that you also do a
set(ALL_TARGETS ${ALL_TARGETS} ${new_target}).

Someone else may have a cleverer solution.
