Have you tried installing SWIPL from the sources at [GitHub - SWI-Prolog/swipl-devel: SWI-Prolog Main development repository](https://github.com/SWI-Prolog/swipl-devel) ?  
Using the instructions at [swipl-devel/CMAKE.md at ff1c2009545e0ec1cf21a0c83d54ddb0e3e4192c · SWI-Prolog/swipl-devel · GitHub](https://github.com/SWI-Prolog/swipl-devel/blob/ff1c2009545e0ec1cf21a0c83d54ddb0e3e4192c/CMAKE.md)  
and in particolar [swipl-devel/CMAKE.md at ff1c2009545e0ec1cf21a0c83d54ddb0e3e4192c · SWI-Prolog/swipl-devel · GitHub](https://github.com/SWI-Prolog/swipl-devel/blob/ff1c2009545e0ec1cf21a0c83d54ddb0e3e4192c/CMAKE.md#finding-requirements) I was able to run Janus.
