Don't put it like that, this was not personal. However, it is also true that 
RPATH changes were typically done by you (according to svn blame) throughout 
KDE (mostly due to your setup as far as I can tell) so this comment ended up 
kind of directed at you.

Well, the issue has already been brought up before on kde-buildsystem. Now I 
tried to find a thread about it and maybe that was by Fedora 
packager. I wasn't quite able to discuss that then, later I forgot and when I 
faced that problem later with KDE 4.4, I needed a fast solution which end up 
being patching out CMAKE_INSTALL_RPATH everywhere. This thread just reminded 
me of that problem again and it would be great if there was a long term 

FWIW, I don't think that this is a problem *only* for debian packaging. It is 
generally not a good idea to set RPATH when library is being installed to a 
standard location on the system because then administrator is not given a 
chance to override this setting. RUNPATH improves things a bit but still, 
/usr/lib R(UN)PATH is not only useless but also harmful. Read more about this 
at (btw, referenced two mails before).

Well, it is hard for me to do (or test it) since I don't have such setup which 
needs so many RPATHs. I believe that cmake defaults ( no install rpath ) meet 
debian's and majority of distros needs completely.

I also think that cmake itself could benefit from more smart RPATH handling 
like that. That stuff in akonadi trunk (which I found completely by accident 
btw) is completely acceptable solution and as I said before, if it was 
deployed in the rest of KDE/kdesupport, I would have nothing to complain 
about. I also see how it should work in your setup as well.

Yes, I know that I could do things better. But in my defence, install rpaths 
are not default (there must be reason for it?) in cmake and other projects do 
not seem to enable it so extensively. So it more looks like KDE problem rather 
than cmake problem. Though cmake could be smarter in this case.

I'm satisfied by this. The quick question was if it had been implemented in 
the rest of KDE trunk / kdesupport trunk as well. That's because I don't 
follow trunk development but probably will only get to it when 4.5 is about go 
out. Your last mail seemed like you somewhat didn't want to ack. that there 
was a problem and offered CMAKE_SKIP_RPATH as a solution.
