If you're building with cmake, you should be using the cmake portgroup which takes care of this for you. Add to the portfile beneath the "PortSystem 1.0" line the line "PortGroup cmake 1.0". Then remove the things which this portgroup takes care of for you, which are "depends_build port:cmake", "configure.cmd cmake", "configure.pre_args", "configure.args -DCMAKE_INSTALL_PREFIX:PATH=${prefix}". If you need to set additional configure.args, be sure to use configure.args-append so you're not overwriting the portgroup's configure.args.
