Polybar: CMake fails to build: No package 'cairo-fc' found. All dependencies are installed.

Hello.

I'm attempting to build Polybar on Fedora 25. CMake returns:

I have installed all packages listed under the dependencies header.

sudo dnf install cairo reports Package cairo-1.14.8-1.fc25.x86_64 is already installed, skipping.

Help would be greatly appreciated. Thank you!

Try installing cairo-devel or cairo-dev

In case if anyone reached here for error faced in Ubuntu:

Use the below command to have cairo installed on Ubuntu.
sudo apt-get install libcairo2-dev

Recently ran into a similar issue. I traced the segfault back to missing libcairo2-dev.

Dug a bit deeper to find that my recent install of Firefox 58 upgraded libfontconfig1 to version 2.12. Libfontconfig1-dev (on which libcairo2-dev depends) requires libfontconfig1-dev version 2.11.0-6.7+b1.

I'm currently running an older version of Firefox, as Quantum requires 2.12 fontconfig1. Has anyone found a way around this?
