Bug 23486 – LINK : fatal error LNK1104: cannot open file '..\generated\windows\copyimports.exe'

The introduction of copyimports.d introduced a build regression. This happens quite often, and only intermittently works.

This has failed for the third time in a row now when running build.

This is blocking release again for v2.102.1-beta.1

This would have been fixed by 30cca65a69821fbc91846ce3423faaae24106a6d FYI @kinke.
