BUG: Build fails on `xyz` with `abc`

[Mukulikaa]

Describe the issue:

Build fails on xyz with abc

Reproduce the code example:

export CC=/path/to/gcc7
python setup.py build

Error message:

Defaulting to user installation because normal site-packages is not writeable
Processing /autofs/nccs-svm1_home1/[...]/numpy
  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.
