trying to build on Windows

[tjwilli58]

Issue: I'm trying to modify the recipe to build gstreamer on Windows. I'm using the pattern done by @pkgw when he modified the recipe for pygobject.

When I try to build, it looks like the environment isn't set right, because %PYTHON% is empty,, but if I try conda debug the environments do define %PYTHON% and %BUILD_PREFIX%, and running conda_build.bat ALMOST finishes.

Environment (conda list):

How about opening a pull request against this repo with your candidate changes? It's OK if the initial version isn't fully baked. That way all of the build logs and your recipe will be accessible in the cloud, so it should be easier to identify problems and work through them.

Wiil do. I got a little further since my post by adding python, meson, and glib to build requirements for the entire project. I then realized this morning that I should have a script for each output, instead of using bld.bat for the entire menu. (Haven't tried that yet though.)
