Version: 3.0.1 (using KDE KDE 3.1.4) OS: Linux The QMake Manager offers no ability to define and edit QMake-".extra" tags to a specified install-target. Once included manually into the .pro-File they will be overwritten by KDevelop.
Can you check wether this still happens with the current SVN version or rc1?
No answer from reporter and we don't screw up .pro files in 3.4 (it should actually be possible to add the .extra thingie via the custom variables)
