You will also need to use this gmake:


http://www.cmake.org/files/cygwin/make.exe-cygwin1.7


At some point support for paths with drive letters was removed from the 
gmake that came with cygwin, so the makefiles do not work  with stuff 
like this: c:/path.  The VS compiler needs that to work.  There was a 
patch in the upstream gmake and the above make has that patch.  I have 
not tried recently to see if cygwin updated make to work again. 
However, I use Unix Makefiles with VS and gmake all the time, but I use 
the above gmake.

To create the environment I started a vsvars.bat type shell, and dumped 
the environment.  I then convert that dump to a bash script.


Something like this:

export INCLUDE='c:\Program Files ...
export LIB='c:\Program Files (x86)\Microsoft  ...
export LIBPATH='c:\Windows\Microsoft.NET\Framework ...
export PATH='/cygdrive/c/Program Files (x86)/Microsoft Visual Studio ...
export DevEnvDir='c:\Program Files ...
export VSINSTALLDIR='c:\Program Files (x86)\Microsoft Visual Studio 9.0'
export WindowsSdkDir='C:\Program Files\\Microsoft SDKs\Windows\v6.0A\'
export VCINSTALLDIR='c:\Program Files ...
export Framework35Version=v3.5
export FrameworkDir='c:\Windows\Microsoft.NET\Framework'
export FrameworkVersion=v2.0.50727
