Recently, I tried to set up `dcv` with `dub` to improve a few
things in the library, but I faced some strange issues.
When doing `dub add dcv`, it works fine. But when I try to add a
local dcv project folder, or a repository, it fails to link the
necessary package libraries. Seems like it's only `ffmpeg`
libraries that are not linked.
What am I missing here?
```
// dub.json
...
"dependencies": {
"dcv": {
"repository": "git+https://github.com/rillki/dcv.git",
"version": "~master"
}
},
...
```
Output:
```

First things first, dcv is added to the dub-registry, so use this. https://code.dlang.org/packages/dcv ```json "dependencies": { "dcv": "~>0.3.0" } ``` For ffmpeg the binding tells you what to add for search paths in the lflags directive. https://github.com/ljubobratovicrelja/ffmpeg-d#adding-to-dub All I can suggest is make sure you have the right dev packages for ffmpeg installed and findable by the linker.

How do people usually set up their projects for such tasks?

How do people usually set up their projects for such tasks?1. git clone to a local directory (use your fork, so you can change and submit when you want to do a PR) 2. CD to that directory 3. `dub add-local .` Now it will use the local directory as the equivalent of the latest tag instead of downloading from the repository. You may have to `dub upgrade` your project that depends on it, or temporarily depend on a different version. -Steve

I have an opinion that the docs should be updated before creating a new version updating the dub repo. There are so many API changes between the last dub repo version and the master repo. I don't know if I will find time and motivation anytime soon. I doubt someone else will do it too (it is a huge welcome though).

[...]I recommend adding DCV sub packages separately. Don't add the entire thing to your dub dependencies. Just only add what you need. Ffmpeg-d in only needed for DCV videoing. You can add subpacks like: "dependencies": { "dcv:core": ..., "dcv:plot": {"path": "../../"}, "dcv:imageio": {"path": "../../"}, "mir-random": "*" }
