C++ boost build errors

we use boost1.46.1 in our c++ project. When I am building my c++ project using cmake, I am getting following errors.

I am not sure why I am getting this error. Can any one please hemp me to fix the following errors?

It looks like boost::regex sometimes depends on the ICU library. You can either link against that library, or you can follow the instructions in the link to disable ICU.

Your Boost.Regex is built with Unicode support — you need to link to ICU as well.
