CPack naming not working for FreeBSD

I am having problem with CPack in that the output file does not get the right name for FreeBSD

This is the CMake command line

cmake -DBUILD_FREEBSD=1 -DOS_DIST=freebsd -DCMAKE_BUILD_TYPE=RELEASE ../oorexxSVN

In CMakeLists.txt I have inter alia the following variables set, listed here for debug purposes:

-- Building for FreeBSD
-- CPACK_FREEBSD_PACKAGE_NAME oorexx
-- CPACK_PACKAGE_RELEASE 12340
-- CPACK_PACKAGE_FILE_NAME oorexx-5.0.0-12340.freebsd.amd64
-- Configuring done

I have attached the complete CMakeLists.txt

However, after a cpack ./ what is built is oorexx-5.0.0.pkg, not ooRexx-5.0.0-12340.freebsd.amd64.pkg as I would have assumed.

These are the folders and files created by the cpack command:

_CPack_Packages
└── FreeBSD
    └── FREEBSD
        ├── ooRexx-5.0.0-12340.freebsd.amd64
        │   ├── +MANIFEST
        │   └── usr
        │       └── local
        └── oorexx-5.0.0.pkg

CMake was built from source

cpack -version -> cpack version 3.22.1
uname -v -a ->
FreeBSD osboxes 13.0-RELEASE-p4 FreeBSD 13.0-RELEASE-p4 #0: Tue Aug 24 07:33:27 UTC 2021     root@amd64-builder.daemonology.net:/usr/obj/usr/src/amd64.amd64/sys/GENERIC  amd64

Am I missing some settings or are there definitions missing here?

I have attached some further file fyi.cmake_install.cmake
