The name of the 'netgen' executable collides with an older UNIX pcb
trace routing application also named 'netgen'. Fedora, for this
reason, renames this mesher package to 'netgen-mesher' and the
executable, likewise, to 'netgen-mesher'. I propose the same change
here.
Ironically though, the current python module is already named
'netgen-mesher', which complicates loading of the module as 'netgen',
often resulting in it being unfindable. For this reason, I similarly
reverse the usage, renaming the python module from 'netgen-mesher' to
'netgen'.
that's also where the shared libraries are, otherwise cmake won't find
the libraries when building NGSolve
(different directory structure and relative paths depending on
system/user/venv package install)
These files are already installed/packed by skbuild (and possibly into another
directory, leading to confusion/not finding shared libraries at
runtime)
