You could try one of several things:

1) Running with a different generator, such as one of the Visual Studio
   generators or the Ninja generator, or
2) Installing NMake.

However, I am a little curious about what you're doing in your use
case. You say you're not building anything. Does your sofware exist in
the form of scripts (Python, Perl, etc.), or are you downloading pre-
built binaries from somewhere?

Without knowing more details about what you're doing, it's possible
that dashboard scripts might be more suited for your use case... though
I see you have a -S argument at the end of your ctest invocation but no
script after it... what's the purpose of this?

See https://cmake.org/cmake/help/v3.13/manual/ctest.1.html#dashboard-cl
ient-via-ctest-script for details on dashboard scripts.
