MacOS

Xcode developer package: Xcode is found on the Mac App store. Install command line tools through the XCode preferences and/or running in a terminal xcode-select --install

Windows

ROOT 6

CMake (version >= 16.3)
Microsoft Visual C++ (ROOT6 requires at least Visual Studio 2019 version 16.1). The Community version is free, fully-featured for students, open-source contributors, and individuals. The Desktop Development With C++ workload is also needed. You can install it directly from the Visual Studio Installer
Python (see here for info on supported Python versions)

ROOT 5 (deprecated)

If you are using Windows make sure you have installed Microsoft Visual C++ (e.g., the no-cost edition) plus CMake. The CMake build will work directly without the need to install cygwin as it was required previously before the adaption of CMake.
