TDE CMake learning Q - How does 'install ( FILES...' put things in 2 places?

Guys, I'm making headway figuring out CMake so I can be a bit more helpful. I'm currently reverse engineering kruler (it's small enough to learn with). So far, the kruler CMakeLists.txt is easy to follow, but I can't figure out how the following creates 2 files?? install( FILES kruler.desktop DESTINATION ${XDG_APPS_INSTALL_DIR} ) /opt/trinity/share/applications/kde/kruler.desktop /opt/trinity/share/applnk/Graphics/kruler.desktop Is there something that says if to ${XDG_APPS_INSTALL_DIR} put it in both the following places: /opt/trinity/share/applications/kde/ /opt/trinity/share/applnk/Graphics/ The other install ( FILES... just end up in one place. (eg. install( FILES eventsrc DESTINATION ${DATA_INSTALL_DIR}/kruler ) /opt/trinity/share/apps/kruler/eventsrc install( FILES move.wav DESTINATION ${DATA_INSTALL_DIR}/kruler/sounds ) /opt/trinity/share/apps/kruler/sounds/move.wav What's the difference? -- David C.
