Fail gracefully during configuration if 'scdoc' is missing #220

Closed Smattr closed 9 months ago

Prior to this change, compilation would fail midway through when trying to run scdoc. This change uses a follow up check and FATAL_ERROR instead of REQUIRED to find_program because REQUIRED was only added in CMake 3.18.
