caption/caption.h missing

[KristijanZic]

I've tried building it on Ubuntu 20.04 and it errored out with this:

$ make

And on NixOS:

Same on Arch and Manjaro

Install libcaption to fix the issue. Either from here, or use AUR on Arch and Manjaro.

Workaround assuming you have obs-studio source copied with git clone --recursive https://github.com/obsproject/obs-studio.git) in the same directory as obs-gphoto:

cd src/
ln -s ../../obs-studio/deps/libcaption/caption
