WIP conda-build.

Have been iterating build.sh

Current issue is that when a venv is being setup to build the wheel, setuptools cannot be found despite it being installed by conda via requirements.

Trying to install setuptools via pip fails too.

Similarly, cmake can't find conda installed SWIG, however requires it be conda installed to allow build to suceed.

May be able to address this one by manually locating paths to pass to CMake.
