Upstream dead since forever. Last update on PKGBUILD in 2015.
Looking at the upstream project on Savannah, there was a spate of activity on 2016-04-17 through the next three days, which replaced the build system with cmake. Please see if you can fix the build first.
Considering how alive things are(n't), it is well justified to update to the latest commit snapshot -- if upstream isn't alive enough to determine whether it is releaseworthy-stable, then the package maintainer can make that determination instead.
