[Linux] deb/dpkg package should not depend on libmpv-dev

[psychonaut]

Describe the bug
DEB package should not depend on libmpv-dev but on libmpv2. Packages that are not development libraries should not depend on -dev packages because it creates huge, necessary dependencies.

Expected behavior

libmpv2 is a sufficient dependency.

[alexmercerind]

So, does that mean I should only depend on libmpv2 & not mpv & libmpv-dev like I've done right now?
Celluloid also seems to only depend on libmpv2.

Thanks a lot!
I will get this over the line quicky along few other urgent changes.

Exactly, unless you directly use mpv as binary libmpv2 is enough.

[alexmercerind]

So... It seems that libmpv2 isn't available on my distribution (& likely many others) & it's called libmpv1.

This situation creates ambiguity. While depending directly upon libmpv-dev automatically transitively resolves the correct shared library package i.e. libmpv2 or libmpv1. I think it's the safest move for now.

Additionally, AFAIK libmpv-dev only adds additional headers for download (which I believe is fine; few KBs).

Do you want to continue? [Y/n] 

it actually means that many packages and 28.3MB

I can see that libmpv2 is in Debian unstable/testing so it will be released in the next stable ubuntu and derivatives.

I think it's possible that actually it should be libmpv1 which is also available but it would need some investigation to check.

[alexmercerind]

I thought about getting this out with today's update, but I kind of lost it when I couldn't locate libmpv2. 😄
libmpv-dev seemed the safest approach for now. Let's see what can be done.

[psychonaut]

I think a usable package with not perfect dependencies is still better than no package at all.
