If built with PREFIX=/usr, then the tests directory installs as /usr/usr/lib64/qt5/tests/qtpass. If PREFIX is ommited, then tests install in /usr/lib64/qt5/tests/qtpass, but qtpass installs as /usr/local/bin/qtpass.
Also, the qtpass.spec file to create rpm package sets PREFIX=%{buildroot}/%{_bindir}, which does not make sense, because everything will install under /builddir/build/BUILDROOT/qtpass-1.2.2-1.fc14.al.x86_64/usr/bin. Example: /builddir/build/BUILDROOT/qtpass-1.2.2-1.fc14.al.x86_64/usr/bin/usr/bin/qtpass.
