Version 2.8.3.20110202-g4d4d5 is a nightly build from the 'next' branch at commit 4d4d51e1. It contains changes to FindQt4 that are *not* in the 2.8.4-rc series.

Does this happen with the actual 2.8.4 release candidate from http://www.cmake.org/files/v2.8/ [^] ?

Yes, you are right. 2.8.4-rc2 is fine.

Sorry for the noise. I promise I'll check which version exactly the coworkers are using next time before filing a bug report. ;)

Any chance I can edit the bug headline?

Fix in git now:
Merge topic 'qt4-fphsa' into next
72e9d3c When checking find_package() components, special case qtmain.

Thanks for testing.
