Set build.dir to that subdirectory. For example, if you need to build in a "build" subdirectory of the main directory, you might use:

build.dir ${worksrcpath}/build

Many ports do these so-called "out-of-source" builds. The cmake 1.1 portgroup has an implementation of it that many ports share, for example.
