[CMake] Multiple install section from the same base folder

[Laszlo Papp]

Hi,

I have just realized this snippet in my CMakeLists.txt file:

install(FILES
    atticamanager.h
    authentication.h

    DESTINATION ${INCLUDE_INSTALL_DIR}/gluon/player/lib
    COMPONENT Devel
)

install(FILES
    archive/archive.h

    DESTINATION ${INCLUDE_INSTALL_DIR}/gluon/player/lib/archive
    COMPONENT Devel
)

install(FILES
    models/commentitemsmodel.h
    models/gameitemsmodel.h
    models/highscoresmodel.h
    DESTINATION ${INCLUDE_INSTALL_DIR}/gluon/player/lib/models
    COMPONENT Devel
)

I wonder whether it could be done smarter. In the example above, there
are subfolders like archive, models. It could also contain 5-10
subfolders (even more) and we install the headers this way: one
separate install section for each subfolder even if we explicitely
write the subfolders all the time, like "archive/archive.h",
"models/commentitemsmodel.h", et cetera.

Are we doing it wrong and there is already a smarter cmake option for
this ? I find it useful if there is just one section for those things,
but if it is technically not possible or against the design, please
let me know.

Best Regards,
