0007 FindSharedMimeInfo
0008 ------------------
0009
0010 Try to find the shared-mime-info package.
0011
0012 This will define the following variables:
0013
0014 ``SharedMimeInfo_FOUND``
0015     True if system has the shared-mime-info package
0016 ``UPDATE_MIME_DATABASE_EXECUTABLE``
0017     The update-mime-database executable
0018
0019 and the following imported targets:
0020
0021 ``SharedMimeInfo::UpdateMimeDatabase``
0022     The update-mime-database executable
0023
0024 The follow macro is available::
0025
0026   update_xdg_mimetypes(<path>)
0027
0028 Updates the XDG mime database at install time (unless the ``$DESTDIR``
0029 environment variable is set, in which case it is up to package managers to
0030 perform this task).
0031
0032 Since pre-1.0.0.
