When the qt-cmake-standalone-test root project is configured in-source
in the source directory of a test A, where test A ends up being added
via add_subdirectory(A), this causes the SUBDIRECTORIES property of A
to contain itself for some reason.
Recursively iterating over the root project's subdirectories thus
causes an endless recursion.
Make sure to remove the currently processed directory from the
retrieved SUBDIRECTORIES property when the function is called
during qt-cmake-standalone-test configuration.
We limit it just for that script, so that we don't accidentally
increase the configure time when building all standalone tests, and
call list(REMOVE_ITEM) too many times.
