Great!

This is expected for any Windows platform that wants to run scripts.
Windows does not support shebang lines so the interpreter must always
be specified explicitly.

As I said in earlier responses this is simply a requirement and is not
likely to change.  I understand your desire to automate the environment,
but I do not think CMake is the right level to achieve that.

The "Unix Makefiles" generator refers exactly to unix-style make tools,
and on POSIX systems is the only generator besides Ninja (excluding the
"extra" generators that use makefiles+project files).  It is available
on Windows because there are make tools on Windows that work with such
paths/shells natively.  Unless ninja were to have a variant that does
so too, then it does not need a distinct generator.
