Well, FWIW, with the CMake-based projects I've been building here 
(Windows10 64-bit, Cygwin 64-bit, packages gcc 5.4.0-1, cmake 3.3.2-1, 
GNU make 4.2.1-1), it has worked just fine, and still does.  I've built 
the current upstream release version of cmake itself with it, among 
quite a number of things.

One possibly important difference is that you keep your source tree in 
the Windows user profile directory; I never subscribed to that idea.

What this brings to mind is that maybe an antivirus program or other 
BLODA is getting in the way here.

The linker command looks pretty much exactly like the one that works 
around here.
