Setup:
1) qt 5.3.1 is built in some local directory (assume c:\dir1\qt\qtbase)
2) I have copied full source tree into other PC (PC2).
3) in the qtbase/bin/qt.conf I have added followed text:
[Paths]
Prefix=c:/path_to_dir2/qt/5.3.1/qtbase
4) qmake seems to work now. Output of the "qmake -query" command contains valid paths only (paths for PC2)
5) I have added into pro-file of one of my projects: QT += widgets

Steps:
1) run qmake

Expected:
1) qmake output is clear. Makefile doesn't contains paths from PC1

Actual:
1) qmake produced lots of messages:
The system cannot find the path specified.
2) In generated Makefile path to uic.exe is incorrect. It is like: c:\dir1\qt\qtbase\bin\uic.exe.

Note 1:
Paths to other tools like moc and rcc are correct. Problem with uic.exe only.
Note 2:
vcxproj also is incorrect.

If line "QT += widgets" is removed from pro-file then Makefile doesn't contain steps for uic'ing ui-files!!! In the vcxproj custom build steps for ui-files are empty.

Any quick workaround will be appreciated.
