> While trying to build Qt Webkit sources from Qt 5.5.1 as a separate module being part of Qt 5.12.7 sources, it throws below error:

Please do NOT use QtWebKit 5.5.1. It has unpatched Spectre/Meltdown
vulnerabilities, as well as a number of rendering bugs.

If 5.212 branch doesn't fit for some reason, you may want to use (as a last resort!)
the head of 5.9 branch, which includes aforementioned fixes.
