I has installed expat libxml2-dev libfreetype6-dev fontconfig fontconfig libxml2 libXpm*

It looks like you need to install an expat development package.

Thank you, I have installed the expat package, I found the solution:
$ sudo apt install pkg-config libasound2-dev libssl-dev cmake libfreetype6-dev libexpat1-dev libxcb-composite0-dev

the solution from https://community.amethyst.rs/t/default-amethyst-new-name-programm-has-trouble-compiling/532

Thanks !
