[CMake] QTCreator project to VS2008 problems

[Michael Jackson]

You may want to take a look at the following sample project:

http://www.cmake.org/Wiki/images/2/25/QtTest-Package-Example.zip

While the project was geared towards OS X specific topics the project  
will compile and run on any platform that Qt is supported on,  
Including MinGW and Visual Studio.
