Windows CMAKE (CTL) failing

I am unsure if this is the right list, but compiling CTL and OpenEXR_CTL 
fails, with the following error:

The first error is the macros failing due to not finding a default 
constructor (it seems Name(const char* l = 0, .... ) is invalid ).
The second error (in the .cpp file) is puzzling as the right includes 
are included (stdio.h and stdarg.h), but maybe not in the right order.

The compiler I am using is VC10 Express.  Maybe I need to upgrade?
