xdg question w.r.t cmake

[Alexander Neundorf]

Hi,

in FindKDE4Internal.cmake we have:

_set_fancy(XDG_APPS_INSTALL_DIR             "${SHARE_INSTALL_PREFIX}/applications/kde4" ...
_set_fancy(XDG_DIRECTORY_INSTALL_DIR   "${SHARE_INSTALL_PREFIX}/desktop-directories" ...
_set_fancy(XDG_MIME_INSTALL_DIR            "${SHARE_INSTALL_PREFIX}/mime/packages" ...

How related are these ?
Would it make sense to give them a common base install directory, which could 
then be different from the KDE share install dir ?

How related are shared-mime-info, the icon cache and e.g. xdg-utils ?
Would it make sense to put the support stuff for them (macros, finding the 
executables, etc.) in one common FindXdg.cmake file ?

Bye
Alex
