I wonder if you can specify a selector on a dependency within a conda package recipe to only select it, if a given package is installed within the installation environment target.
So image a recipe like this:
package:
name: foo
version: 1.0
requirements:
run:
- python
- my_dep_which_requires_something # [ installed(jupyterlab>=3) ]
As you see the last line contains a requirement, which should be optional upon an already installed package named "jupyterlab". Eventually this is already implemented, but I'm unaware of it/ was unable to find it - or it has to be designed/written first.
Glad for any answer pointing me towards the right direction.
