install avogadro with qt4

[lina <lina.lastname@gmail.com>]

Hi all,

I am interested in the old avogadro, instead of the current avogadro2 in bullseye.

The link is here

https://sourceforge.net/projects/avogadro/files/latest/download

However, it needs qt4 support, which is the standard way to proceed with the qt4, which is not supported in the current stable version. Mine system is "stable" version.

Thanks for your help, lina
