[CMake] conflict between configure & build steps in gitlab-runner script for Windows: Debug or Release build directory not found

[Craig Scott]

You have put -j8 before the --build option, but the --build option must be
the first one. This ordering requirement is stated in the docs
<https://cmake.org/cmake/help/latest/manual/cmake.1.html#build-a-project> for
the --build option in the "Build A Project" section.
