Reproducible: Always

Steps to Reproduce:
1. Run PKGBUILD from Arch Linux AUR
2. The programs starts to build successfully 
3. When building the lensfuncameraselector.cpp there are errors and build fails

Actual Results:  
The build process stops with errors

Expected Results:  
Successfully build digikam as usual
