Qt compile ERROR. Please please help

Hi, I'm trying to compile Autodesk's modified Qt 4.7.1 for Maya 2012 Sp2. In VS Command Prompt, I ran thecode:

C\qt-adsk-4.7.1> configure -platform win32-msvc2008 -release -no-qt3support
and it configured successfully. Then I typed nmake in the VS command prompt and it compiled for 6 hours and stopped at this error:


mt.exe : general error c101008d: Failed to write the updated manifest to the resource of file "......\bin\dumpcpp.exe". The process cannot access the file because it is being used by another process.
NMAKE : fatal error U1077: "C:\ProgramFiles SDKs\Windows\v6.0A\bin\mt.exe" : return code '0x2'

Please please someone help. I've tried the the 6 hour compile session twice now.

solved it finally.  I created PATH variables to the C:\Qt, C:\Qt\bin, C:\qt-sdk-4.7.1, C:\qt-sdk-4.7.1\bin directories.
