No, the problem is different: this is not about setting the path to Qt
or other installed libraries, but instead to set the path to uninstalled
libraries:
Think of a layout like this
/
/src
/src/first.dll
/src/tests/firsttest.exe

This would require setting the path to /src and all other such library
directories where libraries exist that are linked to firsttest.exe.

no, making softlinks (ln -s) inside the tests directory.

One of the problems of PATH is that it is size-restricted: max. 2047
chars (think of 20 library destinations à 100 chars) according to
http://support.microsoft.com/kb/830473 (it could actually also be the
mentioned 8k chars, but this is probably dependent on Windows version).
My default environment script already sets PATH to a length of 1400 chars...

If you ensure that there are no more than a handful of library
destinations, this might of course be ok.
