I have the same problem in Debian 9. Here the full ouput of building a simple application if it helps.

Yeah well, it's more of a problem that should be reported to servo-fontconfig-sys, shouldn't it - I can't do much about the bugs of a dependency.

[adrianromero]

Oh!, Thanks for the clarification. I will review Fontconfig-sys tracker.

For what it's worth, I was able to install it with the following packages. Not sure which are actually necessary, though.

sudo apt install libfontconfig1-dev fontconfig-config fontconfig vflib3-dev
sudo snap install cmake --classic

This is because the master branch has an old dependency to servo-fontconfig-sys.

Checkout the unvendor_dependencies branch and build from that, it's more up to date. That let me compile everything on debian.

I have replaced fontconfig-sys with rust-fontconfig, which is a pure-Rust rewrite of the relevant fontconfig functions that azul uses (selecting and querying fonts). Since fontconfig-sys is not needed anymore for building azul, I am closing this issue. The master branch has been updated.
