All Windows packages are built with VS2017.
Python packages are built with Python 2.7 and 3.6 version on macOS (from Homebrew), Ubuntu and Windows.
QML packages are built with Homebrew's Qt version on macOS.
QML packages are built with Qt 5.9.1 VS2017 64 on Windows.
QML packages are meant to be put in the QML Import Path. For instance on macOS it should look like '/usr/local/Cellar/qt/5.9.1/qml/Ossia/qmldir'.

Do note use the Github source package ("Source code" link below) to build; instead do a git clone or use 'libossia-src-unix.tgz'. Else the build won't work due to Github not putting submodules in the archive.
