HOW TO BUILD WITH SANITIZERS ENABLED

Use enable_asan or enable_ubsan, etc.

export CC=$(find ~/.conan/data/llvm_tools/master/conan/stable/package/ -path "*bin/clang" | head -n 1)

export CXX=$(find ~/.conan/data/llvm_tools/master/conan/stable/package/ -path "*bin/clang++" | head -n 1)

export CFLAGS="-fsanitize=thread -fuse-ld=lld -stdlib=libc++ -lc++ -lc++abi -lunwind"

export CXXFLAGS="-fsanitize=thread -fuse-ld=lld -stdlib=libc++ -lc++ -lc++abi -lunwind"

export LDFLAGS="-stdlib=libc++ -lc++ -lc++abi -lunwind"
