Our Windows app is using too much memory to be run as 32-bit. We'd like to switch to 64-bit but are limited by OpenCV being built as a 32-bit dll. I've been told a 64-bit Windows app can't call a 32-bit dll. Is it possible to build OpenCV 3.4.2 as a 64-bit dll? I've looked through the options in CMake, but don't see anything obvious.
