the import of oxygen to kdelibs/ broke compilation with CMake 2.4.3, since
there INSTALL(DIRECTORY ... ) is used which was introduced in CMake 2.4.4.
Our required minimum cmake version is still CMake 2.4.3, so I committed a
quick fix to unbreak compilation.
version 2.4.5, I don't where the one who wrote this got this from.
If you think you found a place where CMake 2.4.3 has a bug or a feature we
really need has been implemented since then, please bring it up an
kde-core-devel or kde-buildsystem.
Please don't silently add stuff which breaks compilation with older version of
cmake than yours and hope that people will just update cmake because it
In kdelibs/cmake/modules/FindKDE4Internal.cmake there is the line
cmake_minimum_required(VERSION 2.4.3 FATAL_ERROR)
which says which version of CMake we require.
So if we require a newer version then this is the line which absolutely HAS to
be adjusted so that the user gets a usefull error message instead of just a
broken build due to whatever reason.
If we then find that we really need to raise the required minimum version then
we'll announce it on k-c-d, kde-buildsystem and kde-devel and do it two weeks
later. I really hate it when I come to my box and just notice that something
doesn't build anymore because some requirement was silently changed.
So, we have now exactly two things were we have advantages with CMake >=
1) building the tests, with cmake >= 2.4.5 the targets are always created but
not included in the all target, so you don't have to rerun cmake to get the
2) INSTALL(DIRECTORY ...) in kdelibs/pics/oxygen/ which just installs a whole
directory tree. I don't know if I'll find the time tosay to see if this can
also be done in some way with CMake 2.4.3.
Is there any distro which ships with CMake >= 2.4.5 ?
AFAIK SUSE 10.2 and Kubuntu Edgy Eft ship with CMake 2.4.3 by default, so you
can simply start working on KDE if you installed them.
