[Cin] CinGG + OpenCV build fails with old gphoto includes

1 Nov 2019

      Hello!

I tried to rebuild CinGG with OpenCV plugins, yet build failed like this:

I don't think gphoto2 actually needed for CinGG needs ?

Will try to switch it off ....

Also, question:

can anyone build CinGG with gcc and  -fsanitize=address ?

For me such build (if I added this switch to both CFLAGS and LDFLAGS) failed on gcc 5.5.0 ...

Should I try with clang (llvm 8.0.1)?
