i just apt installed wmaker and ran it from the SLiM greeter since it makes a wmaker.desktop file
the only troubleshooting i had to do to use it better was
cp /usr/share/WindowMaker/plmenu ~/GNUstep/Library/WindowMaker
to be able to edit the submenu
also had to compile some dockapps from source since not all of them worked very well from the devuan repositories
