"libBlackmagicLib.so" not found after Cross-Compiling for Linux

Hello,

i have made an executable with UE5.1 to make some actors in some scenes and then take screenshots of them. I build this executable in Windows and it’s working perfectly.

I want but to make that in Linux. So i cross-compiled the same projectfor linux. Now when i run my “.sh” i get the following error:

error while loading shared libraries: libBlackmagicLib.so: cannot open shared object file: No such file or directory

Any ideas how to solve that?

Thank you very much.
