[Olaf] Wouldn't it make sense to have one VS install, chosen by the user of course, be the default?

The problem is in locating that one VS install.

On Linux one can just do g++ a.cpp, wouldn't it be nice if something similar could be done on Windows?

All kinds of command line tools need to do all kinds of tricks to find other tools it seems (on Windows).

In a (non-Boost) project with which I've helped, there's a script that does the following: 0. The user specifies desired VS version by setting an environment variable to (e.g.) "120" for VS 2013. 1. The script concatenates "VS" + version + "COMNTOOLS" to form an environment variable name. 2. In the directory indicated by that environment variable, it finds VCVarsQueryRegistry.bat. 3. It runs VCVarsQueryRegistry.bat in a child process that reports VCINSTALLDIR to the parent script. 4. Finally it runs %VCINSTALLDIR%\vcvarsall.bat, passing either x86 or x64 depending on the user. If that doesn't work with VS 2017, or for that matter with VS 2015, they'll need an algorithm that *does* work.
