i'm unfamiliar with debian, but when i see errors like that in a Centos env, i usually fix it with the -devel package (so libbluray-devel in this case); afterall your 'developing' a source code build.
fwiw i have found missing packages in the fedora/centos section of the ansible playbook in the past (and submitted a fix) so while it's a very good tool to help setup your system, don't treat it as 100% perfect.
