In your Makefile you need

USE_CMAKE=      yes
CMAKE_ARG_PATH= ..
CONFIGURE_DIRS= $name_of_dir

Then you need a pre-configure or whatever stage to create the build dir

e.g.

pre-configure:
        ${MKDIR} ${WRKSRC}/_KDE_build

The above is taken from pkgsrc/meta-pkgs/kde4/Makefile.kde4.

I suggest you have a look at how the kde4 packages are set up as an example of 
how the CMAKE stuff works.

Hope that helps..
