Error: DIA SDK is missing at "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\DIA SDK". This is due to a bug in the Visual Studio installer. It does not install DIA SDK at "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\" but rather at VS install location of previous version. Workaround is to copy DIA SDK folder from VS install location of previous version to "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\" and then resume build.
Visual Studio Express does not include the DIA SDK. You need Visual Studio 2015 or 2017 (Community is free).
