Unable to link go app against gocv in container

The above is the error that I get when I try to actually build a static go app that is dependent on gocv, I had to overwrite the CGO_LDFLAGS because the development image defined the folder as being -L/usr/local/lib without the 64 part which is wrong for Alpine.

I can see the opencv_core lib in the /usr/local/lib64 folder and its also listed in the CFO_LDFLAGS and yet the linker barfs on them any idea?
