When some package installs a new XML file with mime type definitions in
${XDG_MIME_INSTALL_DIR}, the install procedure should run the script
update-mime-database. This script may be invoked as a post-install step by a
package manager.
That is exactly what happens with my Drumstick library
(http://drumstick.sf.net, it is a dependency of KMid and others). The main
CMakeLists.txt has this line:
INSTALL( FILES drumstick.xml DESTINATION share/mime/packages )
That is only copying the XML file into the destination directory, and must be
processed after the installation. In the provided RPM spec, I have:
PreReq: shared-mime-info
...
%post
%{_bindir}/update-mime-database %{_datadir}/mime
%postun
%{_bindir}/update-mime-database %{_datadir}/mime
So if you have installed it, or a similar library from sources, you probably
missed the execution of the script, and it is my fault (or the authors of the
other package you installed from sources).
There is a CMake macro for this task, update_xdg_mimetypes() that is defined
in FindSharedMimeInfo.cmake. This macro is used in
kdelibs/mimetypes/CMakeLists.txt, so it is already a dependency of KDE.
