Installing rioxarray is a pain because of a dependency on gdal... Trying to install it for QGIS's python version is even more frustrating. I need to install the module for QGIS because I want to build a QGIS plugin using this module.

Trying to install it (`python -m pip install rioxarray`) via the OSGeo4W-shell gives the following error:

```

I'm not quite sure how to provide a path (and which path) to the gdal-config to overcome this problem. What makes it even more confusing is the fact that my computer has 4 different versions of python installed, which are used by different programs and I'm not sure how to tell pip to choose the right version of python, which is used by QGIS. Especially because my computer says (by `py -0`) that QGIS's Python version (3.7) does not exist - but it does exist.

Thank you very much for your help :-)
