There's your culprit -- the back-slash after eggs: it should be

The Chicken 2.41 tarball built on VS71 with nmake -f fails in the same way. This is not a CMake-specific problem. Rather, it's either a general problem with eggs on MSVC, which are making an inappropriate use of a Windows style pathname. My suspicion falls on _make-pathname in utils.scm, but if there's a platform-specific behavior, it's not clear to me.

The platform specific behavior is in library.scm, buried as a primitive:

(define ##sys#pathname-directory-separator
 (let ([st (software-type)])
   (if (and (eq? 'windows st) (not (eq? (build-platform) 'cygwin)))
   #\/) ) )

This is wrong for a URL. I haven't exactly figured it out, but it appears that make-pathname is being used for URL construction, which ultimately ends up with system-specific behavior when it shouldn't. I am still jobhunting / trying to keep a roof over my head / avoid eviction 2 weeks hence. I don't have the time to decide what the proper design should be. Additional eyeballing appreciated.
