I configured & compiled Qt 4.3.5 using MinGW, and I'm running into a problem. I simply moved the directory structure from C:\src\qt-all-opensource-src-4.3.5 to C:\usr\qt-all-opensource-src-4.3.5

but now I can't run configure.exe -platform win32-g++ , as it somehow insists on the old location of mkspecs:

Qt Code: 
  1. Generating Makefiles...
  2. Could not find mkspecs for your QMAKESPEC(win32-g++) after trying:
  3.         C:/src/qt-all-opensource-src-4.3.5\mkspecs
  4. Error processing project file: C:/usr/qt-all-opensource-src-4.3.5/projects.pro
  5. Qmake failed, return code 3

even if explicitly set QMAKESPEC by:

Qt Code: 
  1. set QMAKESPEC=C:\usr\qt-all-opensource-src-4.3.5\mkspecs
To copy to clipboard, switch view to plain text mode 

the result is the same. what might I be doing wrong?
