What follows are the steps I took to build PCRaster on Fedora (34) from source. I chose to build from source because I didn't want to use the conda installer and I could not find a stand alone package.
The process below assumes that you have a working QGIS build environment since some of the PCRaster dependencies are provided by the QGIS dependency tree too.
git clone git@github.com:pcraster/pcraster.git
