Maik,
I just seen that if we compile QtAV with the same compiler warnings level than
digiKam (through KF5::ECM), we obtain the same warnings in fact about undefined
preprocessor rules. Ex :
26 | #if NV_CONFIG(DLLAPI_CUDA)
| ^~~~~~~~~~~~~~~~~~~~~

"defined" may not be portable [-Wexpansion-to-defined]
48 | #if !NV_CONFIG(DLLAPI_CUDA) && !defined(CUDA_LINK)

The guy who code this rules must be ... well, forget (:-)))... You know what i
mean...
