Fail to install compas in ironpython environment

[yck011522]

Started since compas version 2.1.1, the automatic testing workflow in compas_fab fails during installation. This affected only the windows-ironpython environment but not linux. @gonzalocasas also told me that this affected compas_eve too. The failed workflow log can be found here:

    Complete output from command python setup.py egg_info:

    IOError: [Errno 2] Could not find file 'c:\users\runneradmin\appdata\local\temp\pip-rrofyb-build\setup.py'.: c:\users\runneradmin\appdata\local\temp\pip-rrofyb-build\setup.py
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in c:\users\runneradmin\appdata\local\temp\pip-rrofyb-build\

As a test, I have tried to pin the version to 2.1.0 (in this branch: https://github.com/compas-dev/compas_fab/pull/427/files) and the test can pass. So I think it is related to some changes in 2.1.1
