[Work-in-progress]
This is a recipe for building KLayout with GUI on Windows as a conda package using the MSVC2017 compiler and is intended to supplement this effort.
For the time being, the package can be installed from my Anaconda channel with:
conda install -c thomasdorch klayout-gui
This package installs both the GUI (without a start-menu shortcut) and the KLayout Python package to the conda environment so the full KLayout Python API is accessable from the environment.
