Editable builds

[aaraney]

Certain combinations of pip and setuptools versions cause editable t-route builds to fail. This only affects troute.network and troute.routing packages. t-route packages are built in editable mode by default when using compiler.sh. Specify no-e as an argument to compiler.sh to change this behavior.

setuptools==64.0.0 changed the behavior of editable builds. Workarounds:

• Install setuptools<64. Editable builds should work as expected.
• Install troute.network and troute.routing using:

  cd src/troute-network
  python setup.py build_ext --inplace --use-cython
  # note: requires pip>=22.1
  pip install --no-build-isolation -e . --config-settings editable_mode=compat
  cd -
  
  cd src/troute-routing
  python setup.py build_ext --inplace --use-cython
  # note: requires pip>=22.1
  pip install --no-build-isolation -e . --config-settings editable_mode=compat
  cd -
