Enabling Address Sanitizer for OpenCV builds

Is there a way to enable Address Sanitizer for OpenCV builds?

I've tried adding OPENCV_EXTRA_CXX_FLAGS="-fsanitize=address"; however, I receive configuration errors claiming:

Compiler doesn't support baseline optimization flags

I've also tried adding custom build configs like the below:

# AddressSanitize
set(CMAKE_C_FLAGS_ASAN
    "-fsanitize=address -g -O1"
    CACHE STRING "Flags used by the C compiler during AddressSanitizer builds."
    FORCE)
set(CMAKE_CXX_FLAGS_ASAN
    "-fsanitize=address -g -O1"
    CACHE STRING "Flags used by the C++ compiler during AddressSanitizer builds."
    FORCE)

This makes it further, but upon linking libopencv_core.so I get the following error:

Thanks for your time!
