This is a heavily modified, stripped down copy for use with Loton, here: https://github.com/loganmcbroom/Loton
Have Qt installed.
git clone https://github.com/loganmcbroom/nodeeditor
cd nodeeditor
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --target install --config Release
The "-DCMAKE_BUILD_TYPE=Release" is for single-config generators, while "--config Release" is for multi-config generators. NodeEditor also exports the build tree, so "--target install" isn't needed if the build will remain where it was built.
