The MSVisualStudio build is not setup to build the Cbc Ampl driver.

To build the CBC AMPL driver see the faq "How do you build the COIN-OR Cbc
AMPL solver executable on Unix-like platforms (including Cygwin and MinGW)
from the SUBVERSION Cbc code base?" on page
https://projects.coin-or.org/Cbc/wiki/FAQ.

Since you are using windows, you will want to use Cygwin or MinGW.
