autoreconf: error: autopoint failed with exit Status: 2

hello

I try to compile on a raspberry 4 but receive following error near end of compiling.
I am not a professional, so dont know how to solve it.

Start with the reported build output and the referenced libzvbi/configure.ac file, then inspect how the CMake external project invokes autoreconf. Check the Raspberry Pi/DietPi environment for the missing autopoint tool and its dependency setup. Done means the libzvbi patch and build steps complete without the autopoint error.
