Ah, see? I didn't even know what to look for :).

I don't have direct access to the machines, so I can't really check anything 
except the cmake command lines, which are generated by the expect_pass macro 
and similar here: 

 https://qt.gitorious.org/qt/qtbase/blobs/HEAD/src/corelib/Qt5CTestMacros.cmake

which is used here for example:

 https://qt.gitorious.org/qt/qtbase/blobs/HEAD/tests/auto/cmake/CMakeLists.txt

which is used by a cmake command generated here:

 https://qt.gitorious.org/qt/qtbase/blobs/HEAD/mkspecs/features/ctest_testcase.prf


So, how is the target 32bit/64bit determined? An option to cmake at cmake 
time?

Thanks,

Steve.
