I suspect you might be right.  I am thinking this is MSYS messing with 
the command line somehow.  Can you build with nmake and a DOS shell? 
If so, can you then go into that tree with the msys shell and try to build?

Some other things you can try:
add --debug-trycompile to the cmake command line.  This will leave the 
files in CMakeFiles/CMakeTmp.  You can then cd into there and run nmake 
from the command line and look at the makefiles.  I don't think CMake is 
doing the mixed path stuff.  I think this is a bad interaction with 
nmake and msys.
