Installation under windows is not working

[OlorinOLorien]

Description

"cmake -B build" (step1) followed by "cmake --build build" (step2) yields a "Build: 2 succeeded, 325 failed, 0 up-to-date, 0 skipped".

Expected Behaviour

Maybe naively, I expect the installation to work.

Version of stdlib

1d27d27

Platform and Architecture

Windows 11 (of course x64)

Additional Information

I attach console outputs for step1 and step2
step1.txt
step2.txt

You might try turning off build testing and seeing if you can get it to build. To do that:
"cmake -B build -DBUILD_TESTING=Off"
