[CMake] FindQt3.cmake bug - does not recognize uic

[Anka Kochanowska]

Thanks for answering.
Our application is built on different systems. Some of them have Qt3 and 
Qt4, some have not been properly installed, so having the condition 
would be helpful to diagnose the problem.
FindQt3.cmake fails on Ubuntu, Debian and Mandrake. So we comment out 
the condition, but ...
Also, there is no problem with moc and it is treated pretty much the 
same way as uic.
What is your system?
