Comment:
You sure ? Adding this: 

```suggestion
makedepends="libebur128-devel ffmpeg-devel taglib-devel"
```

And then xbps-src package:

>  => loudgain-0.6.8_1: running do_configure ...
-- Checking for module 'libavcodec'
--   
CMake Error at /usr/share/cmake-3.17/Modules/FindPkgConfig.cmake:497 (message):

EDIT:
```suggestion
makedepends="libebur128-devel ffmpeg-devel taglib-devel libavcodec pkg-config"
```

This makes it work
