Additional context
It looks like the configuration tool is searching for libx264.lib but only x264.lib is installed.

Also reported here: #12896

Great to finally see a fix for this!

[a1q123456]

This issue has already be fixed in the PR #13450, so it is better to wait that PR to be merged

[mcmtroffaes]

Ah yup, good catch.

[a1q123456]

Ah yup, good catch.

It is better to wait for that PR, I noticed that the two PR are conflicting. 😄
