The generated Racket-on-Chez executables will have a "cs" suffix
for `--enable-cs`, and it will not have a "cs" suffix for
`--enable-csdefault`. Also, plain `make` will still build the
traditional Racket implementation with `--enable-cs`; use `make cs`

`--enable-csdefault`, plain `make` and `make install` will build

Racket using `--enable-racket=...`.
Chez Scheme is included in a Racket source distribution, but not in
the main Racket source repository. Building Racket-on-Chez requires
either a "ChezScheme" build checkout within the build directory or at
at an alternate location specified by the `--enable-scheme=...`
argument to `configure`. If "--enable-scheme=...` is not specified,
then a "ChezScheme" directory is copied if it exists to the build
subdirectory, otherwise if must be checked out before configuring into
the build directory.
Chez Scheme is included in a Racket source distribution and
`configure` detects that source, so no separate download or Git
checkout is needed in that case.
