That is quite a lot of a code for something as simple as (the ideal case of desktoplinux):

x="-g -fsanitize=address,undefined"; cmake . -DCMAKE_CXX_FLAGS="$x" -DCMAKE_SHARED_LINKER_FLAGS="$x" -DCMAKE_EXE_LINKER_FLAGS="$x"

I agree that it's a lot of infrastructure and CMake code to maintain to add compiler flags, not sure it's a great addition. We have little incentive to have a flawless cross-platform ASAN integration
