I tried on -current with latest pkgsrc and it doesn't build for me in
the same way.

The file is added to the build here:

src/core/CMakeLists.txt:
FILE(GLOB JSON_HELP_FILES "${CMAKE_SOURCE_DIR}/resources/function_help/json/*")

cmake was last updated on August 22, perhaps the update broke it.
If you have an old version lying around, try that and/or contact cmake upstream.
