[boost] [VS2017][release] vswhere.exe

Hi, This is regarding issues with locating VS 2017 toolset(s).

From CMake ml, I learned about vswhere utility being developed by Microsoft

https://github.com/Microsoft/vswhere vswhere.exe (390 KB) is downloadable from https://github.com/Microsoft/vswhere/releases I'm not sure how exactly, but perhaps it would solve some of the Boost.Build's headache (eg. particular PowerShell version required). For example, it can find all VS versions I've got installed (10.0, 11.0, 12.0, 14.0, 15.0): vswhere.exe -legacy find a particular version: vswhere -legacy -version [11.0,12.0) Best regards, -- Mateusz Loskot, http://mateusz.loskot.net
