I have the spdx-tools installed, but I don't need the BOM so I will turn this off.

Hi Scott,

The 
  'WARNING: Qt WebEngine And Qt Pdf SBOM generation will be skipped due to missing dependencies. ' 
warning is shown when sbom generation is enabled, but one of the python dependencies is missing, specifically the spdx-tools package.

If you don't care about SBOMs, you can configure Qt with -no-sbom, or -DQT_GENERATE_SBOM=OFF, that should silence the warning.

Otherwise you can install the dependency with C:/Qt/buildarea/python/python.exe -m pip install spdx-tools.

I've created an issue to track improving the warning message and docs about this situation:
