Hi Sebastian,

The /usr/include/obs/obs-frontend-api.h is part of the obs-studio, not
obs-move-transition. Thus, the obs-studio package has an internal file
(obs-frontend-api.h) pointing to a wrong path. The problem is not in
obs-move-transition.

In other words, obs-move-transition is not ignoring the cmake config
installed by libobs-dev. Let me know how to help you. I think my MR #5
will solve this issue.
