How to compile for vc141 toolset when only Visual Studio 2019 is installed?

[TomArrow]

I like to use the older vc141 toolset for my projects, so I would like to compile Boost with that instead of the automatic vc142. Unfortunately running b2 toolset=141 throws an error:

warning: Did not find command for MSVC toolset. If you have Visual Studio 2017 installed you will need to specify the full path to the command, set VS150COMNTOOLS for your installation, or build from the 'Visual Studio Command Prompt for VS 2017'.

vc141.jam: No such file or directory
C:/Boost/boost_1_77_0/tools/build/src/build\toolset.jam:44: in toolset.using
ERROR: rule "vc141.init" unknown in module "toolset".
C:/Boost/boost_1_77_0/tools/build/src\build-system.jam:543: in process-explicit-toolset-requests

C:/Boost/boost_1_77_0/tools/build/src/kernel/bootstrap.jam:139: in boost-build
C:/Boost/boost_1_77_0/boost-build.jam:17: in module scope

Obviously I have no VS 2017 prompt because VS 2017 is not installed, but I do have the build tools installed. What do I do?

The correct toolset name is msvc-14.1.
