Is your feature request related to a problem? Please describe.
I would like to build kontrolrack and kontrolmodule external for Apple Silicon

[patricecolet]

The pd external is built by doing in root directory
cmake -B build -S .
cmake --build build
and in CMakeList.txt added
set(DISABLE_PUSH2 1)
set(DISABLE_EIGENHARP 1)
and removed add_subdirectory(external/EigenLite/eigenapi)
and finally changed arch set(CMAKE_OSX_ARCHITECTURES "arm64")

But PureData crashes on kontrolRack Connect() method

[patricecolet]

PureData is crashing on KontrolRack_connect(). Meanwhile I can use PureData OSC internal.

[patricecolet]

I'd like to run kontrolRack external with using PureData only, but orac.json couldn't be loaded, so I have to hardcode 'dataDir' path to load presets from json.
