Unknown CMake command "Mathematica_ADD_LIBRARY" on Raspberry Pi 3

[Expander]

Dear @sakra ,

I've found an issue with FindMathematica 3.3.0 on my Raspberry Pi 3 (Raspbian, based on Debian buster, 32-bit): CMake complains:

Unknown CMake command "Mathematica_ADD_LIBRARY"

I've setup the test repository which shows the setup and the error output here: https://github.com/Expander/test-FindMathematica If needed, I can paste more configuration files etc. to trace the issue.

Best regards, Alexander Voigt
