build issue

Hi, I got stuck on the installation when cmake --build build. I have no idea why line 313 says error. Any advice would be very appreciated. Thank you for your support.

On which system/C++ compiler are you building souffle?

Strict warning messages stop the build. You need to disable the warning message using the flag -DCMAKE_CXX_FLAGS=-werror=unused-variable
