 The necessary dependencies are CUDA, ROOT, the Boost libraries, Alpaka, and some CMSSW headers. CUDA, ROOT, and Boost, are fairly standard libraries and are available from multiple package managers. For the remaining necessary headers you will need to clone the [Alpaka](https://github.com/alpaka-group/alpaka) and [CMSSW](https://github.com/cms-sw/cmssw) repositories. The Alpaka repository is reasonably sized, but the CMSSW one extremely large, especially considering that we only need a tiny fraction of its files to build LST. We can get only the Alpaka interface headers from CMSSW by running the following commands.
