Description
After https://codereview.qt-project.org/c/qt/qtbase/+/518683 landed,
trying to call qt-cmake-standalone-test on an in-source auto test (not out-of-source build) like this:
cd qtsvg/tests/manual/examples/svgviewer ~/qt/builds/dev-mac/qtbase/libexec/qt-cmake-standalone-test .
errors out with an endless recursion.
Some debug annotations shows:
>>> CMAKE_CURRENT_SOURCE_DIR /Volumes/T3/Dev/qt/builds/dev-mac/qtbase/lib/cmake/Qt6BuildInternals/QtStandaloneTestTemplateProject >> cuurrent dir /Volumes/T3/Dev/qt/builds/dev-mac/qtbase/lib/cmake/Qt6BuildInternals/QtStandaloneTestTemplateProject >> subdirs /Volumes/T3/Dev/qt/worktrees/dev/qtsvg/tests/manual/examples/svgviewer >> cuurrent dir /Volumes/T3/Dev/qt/worktrees/dev/qtsvg/tests/manual/examples/svgviewer >> subdirs /Volumes/T3/Dev/qt/worktrees/dev/qtsvg/tests/manual/examples/svgviewer >> cuurrent dir /Volumes/T3/Dev/qt/worktrees/dev/qtsvg/tests/manual/examples/svgviewer >> subdirs /Volumes/T3/Dev/qt/worktrees/dev/qtsvg/tests/manual/examples/svgviewer >> cuurrent dir /Volumes/T3/Dev/qt/worktrees/dev/qtsvg/tests/manual/examples/svgviewer >> subdirs /Volumes/T3/Dev/qt/worktrees/dev/qtsvg/tests/manual/examples/svgviewer ....

It's some bad interaction with SUBDIRECTORIES containing the current source dir when configuring in a nested in-source subdirectory (due to how we implemented qt-cmake-standalone-test).
One more reason to get rid of the script.
