[CMake] FindQt in a Specific place?

[Michael Jackson]

Um, yea, you don't want to do that, change the location of the Qt  
libraries after they are built in one location. On Windows, the only  
way you can do that (to my knowledge) is to use the MinGW precompiled  
binaries from Nokia. When the installer runs all the paths are updated  
for the install location. As far as I can tell, Nokia has not released  
the installer build scripts for Qt built under Visual Studio. You seem  
to need a commercial license for that.

  So, With Qt, Pick a location where EVERYONE can have Qt installed,  
build it in THAT location, then you can move the installation from  
computer to computer. Yes, it sucks.
