That would mean it needs to find that file as first thing, because that
file actually uses its own absolute path to set the variables properly. And
at that moment you again have a problem when people have multiple VS
installations on the same machine.

It does support _all_ toolchains in the same way, it expects the toolchain
to be available in the environment in which cmake is executed.

All platforms that cmake supports work the same way. On each platform cmake
expects you to setup your environment for the toolchain you want to use.
Sure its easier on linux because the default version of
compiler+linker+make are automatically available in your environment. As
soon as you want to use a different toolchain you have to go through the
same things as on windows. You can of course also have your development
tools in your default environment on windows as well and maybe MSVS should
offer to do that during installation.
