integration with Conda.jl?

If someone uses the conda-forge Julia with the [Conda.jl package](https://github.com/JuliaPy/Conda.jl) (e.g. this is the default configuration for PyCall and PyPlot on Windows and Mac), it would be nice if Conda.jl automatically realized this and used the same conda environment instead of installing its own?

Is there a good way to detect this when Conda.jl is running [its build script](https://github.com/JuliaPy/Conda.jl/blob/master/deps/build.jl)? i.e. how can we detect if we are running Julia via conda-forge?
