Qt
- install the open source version of Qt
- during installation, install sources and debug info for latest
- rename the kits to just "32" (win only) and "64"
- tools->external->configure, create a "delete build" tool with same command (executable), args, and dir as first (Disabled) build step in kJams, give it a key shortcut of cmd-shift-delete
- open when you open a .pro file it will probably say "couldn't use it", hit ok, close Qt
- open the user file and the now old copy of the previous user file, and copy the good data from the old one to the new one, preserving the new guids and file version IDs
