OUI

OUI is a cross-platform UI engine written from the ground up in C++. It allows you to easily build programs with rich UIs that can be built for many operating systems. The functionality for your program can be written in C++ or JavaScript (coming soon).

Building

To download dependencies run

python3 scripts/setup.py

node-gyp is needed to build OUI

npm install -g node-gyp

then while in the OUI-engine directory:

node-gyp configure
node-gyp build

This will generate binaries for the library in build/Release/ or build/
