I've found that the easiest way is to package your software and use
software like 'mock' (http://fedoraproject.org/wiki/Projects/Mock) to
build the software for other platforms.  Mock builds the software in a
chrooted shell built up using the packages for that distribution, so
you it'd use CentOS6's GCC, boost, cmake and glibc.
