build GMSH with candi

[mamirkiani]

Hi
First, I should appreciate @tjhei for his great work in preparing candi. It makes builidng and installing deal_II very simple.
I am trying to build GMSH package for using in deal_II with candi.sh. but it does not support. I ran this code:
./candi.sh -packages="gmsh"
and get this error in cmd line.
#invalid command line option <-packages=gmsh>. See -h for more information.
my current platform: ubuntu 20.04LTS
I installed default packages with no effort, but i stuck in gmsh.
I think i need to modify candi.cfg. If this is correct, please explain how can I do that.
Sincerely
Amir
