Description Cristian Le 2025-04-30 15:36:26 UTC 
Trying to build psi4 with CMake 4.0 we get a build failure of
```

CMake Error at chemps2_external-stamp/download-chemps2_external.cmake:163 (message):
  Each download failed!

    error: downloading 'https://github.com/SebWouters/CheMPS2/archive/d8ac508.tar.gz' failed
          status_code: 6
          status_string: "Could not resolve hostname"
          log:
          --- LOG BEGIN ---
          Could not resolve host: github.com

  shutting down connection #0
```

This is rather odd since the ExternalProject calls should have been overwritten.

Reproducible: Always
