Hi! I am trying to install corry on a new machine (Apple M1, macOS 11.3.1, AppleClang 12.0.5.12050022). I have root installed and working (can run the interpreter and successfully compiled other frameworks using root),
MacBook-Pro:~ aleopold$ brew info root
root: stable 6.22.08 (bottled), HEAD
Object oriented framework for large scale data analysis
https://root.cern.ch/
Conflicts with:
glew (because root ships its own copy of glew)

==> Caveats
As of ROOT 6.22, you should not need the thisroot scripts; but if you
depend on the custom variables set by them, you can still run them:
For bash users:
. /opt/homebrew/bin/thisroot.sh
For zsh users:
pushd /opt/homebrew >/dev/null; . bin/thisroot.sh; popd >/dev/null
For csh/tcsh users:
source /opt/homebrew/bin/thisroot.csh
For fish users:
. /opt/homebrew/bin/thisroot.fish
Emacs Lisp files have been installed to:

Now when I try to compile corry tag v2.0.1 (after running from a build directory cmake .. with no errors) I get

I tried to google the error and tested a couple of cmake flags suggested in some threads, but nothing helped. Would be happy if anyone had a hint!
Best,
