%ctest macro seems not accepting any arguments, making it impossible to pass arguments to ctest program in a spec file:

# rpm --eval '%ctest -V'
error: Unknown option V in ctest(:-:)

cmake-rpm-macros-3.26.5-2.el9.noarch defines the macro like this:

%ctest(:-:) \
  cd "%{__cmake_builddir}" \
  %__ctest --output-on-failure --force-new-ctest-process %{?_smp_mflags} %{**} \
  cd -

I'd like to pass -V option to the ctest program at the place of %{**} macro.

I think the bug is in an option string of the %ctest macro definition. It should be a dash only without the colons, like in this example:

$ rpm --define '%foo(-) before %{**} after' --eval '%foo -V'
before -V after

This is similar to RHEL-10 bug RHEL-85715.
