Using bls-signatures as a dependency does not work on Windows

[ktechmidas]

My understanding is that this is caused by no quotes around the post-build task, making it fail with a strange error

echo VCTargetsPath=C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\ :VCEnd The network path was not found.

Caused by:
  process didn't exit successfully: `C:\dash-evo-tool\target\release\build\bls-dash-sys-38d764f1db0bcbff\build-script-build` (exit code: 101)
