Not sure about this one -- your guess sounds reasonable, though. The
cygwin tools work well under cygwin, but maybe or maybe not so well
when used directly from a windows cmd prompt. (Vice versa, too :
windows tools work well under windows cmd prompt, but maybe not so
well under a cygwin shell... many reasons for this... but the lesson
is usually : use cygwin tools when in a cygwin shell, use other tools
in other shells. :-)

I'm not sure about these two questions either. Cygwin does not appear
to have a "gmake", unless it is buried inside some other package that
is non-obvious simply from scanning through the list of available
cygwin packages....

I'm not sure what the reason behind it is (other than perhaps most
Unix/Linux developers  prefer gmake over make...?) but the
implementation is clear from CMake's Modules/CMakeUnixFindMake.cmake :
  FIND_PROGRAM(CMAKE_MAKE_PROGRAM NAMES gmake make smake)
  MARK_AS_ADVANCED(CMAKE_MAKE_PROGRAM)

Directing cmake to the right make with -D is a good solution for you
if you want to keep your PATH set as it is...

HTH,
