Don't use the obsolete LOCATION property since it might have subtle
side effects, see [1]. Instead, use the new "generator expressions"

ADD_CUSTOM_COMMAND(TARGET fubar POST_BUILD
    COMMAND ${CMAKE_COMMAND} -E copy $<TARGET_FILE:fubar> somepath)

or follow the advice Michael W. has provided in the meantime.
