The msys cmake is a different beast than the mingw cmake (both will have
either
X86_64 and i686 versions). The msys cmake is a modified version that does
not
include the "MSYS_Makefiles" generator and instead defaults to "Unix
Makefiles". But then,
"MSYS" is a defined variable in the attached cmake scripts, at exactly the
places a "CYGWIN"
variable would be used in the root cmake code distribution.

Both are made via the bash environment provided by msys. the CMD
environment is to be used
with the "MINGW Makefiles" generator, requiring a different setup of path
etc. than just
a plain MSYS.

4.9.2. It probably was
updated then if gcc is now 5.3 there. These versions should be following
cygwin -
but I see cygwin is using gcc 5.3.05 but only cmake 3.3.1, so 3.5.2 is
jumping a little ahead.
