Generate a static website for the unit test ran via CMake

**Describe the feature you'd like**
Once the testsuite ran via cmake, we should generate the static webpage for the test, similarly to what we do with scons.

**Describe the solution you'd like**
We need to separate the static page generation from scons and ran it after the testsuite.

Start by tracing how the unit tests are run through CMake and how SCons currently generates the static test webpage. Identify the shared page-generation work that can be separated from the SCons flow, then determine where it should run after the CMake testsuite. Done means CMake test runs produce the same kind of static webpage as SCons.
