[conda] Configuring PATH / LD_LIBRARY_PATH environment variables in `conda develop`

[E. Tadeu]

Conda allows adding a python package in "development" mode through `conda
develop` by adding its directory to a conda.pth file (effectively the same
as adding it to PYTHONPATH).

Is there a way to also add directories to the PATH environment variable?
This is for projects that use a mix of C++ and Python, and have some shared
libraries that are not python extensions and that must be in the PATH in
Windows platform (or in LD_LIBRARY_PATH in Linux).

Thanks!

No, there is no way currently to set PATH or LD_LIBRARY_PATH. It is not
clear to me which path should be added (prepended) to those environment
variables. But you can add a little bash script (which you then source) to
your project, which does whatever is necessary.

Thanks for the quick answer, Ilan. The path to be added would be a
subdirectory of the project, such as `bin`.

Considering the script solution, is there a way for the `activate` command
to automatically source this script? Something like the
`/etc/conda/activate.d` mechanism, but for development projects instead of
conda packages.

Cheers,
Tadeu
