YAML for C - libyaml

I am trying to parse information from a .yaml file into C but even after installing libyaml to the computer <yaml.h> can’t be found. I’m just wondering how I can get yaml support on platformio to parse into C.
libyaml - http://pyyaml.org/wiki/LibYAML

I am developing on a Sodaq ExpLoRer. Using Platformio on Atom on Linux (Elemantary OS - Ubuntu).
Thank you in advance!
