我有一些依赖项需要使用cmake进行编译，但我不确定是否正确。我目前在CFLAGS中使用-march=x86-64 for amd64，这似乎可以正常工作，但我不确定是否正确，因为当我尝试以新的M1为目标时，它无法正常工作。我是否应该做些其他事情来从命令行使用cmake来针对不同的体系结构？

export CFLAGS="-O2 -march=aarch64 -fomit-frame-pointer -fno-stack-protector -pipe"

cmake -B ${{github.workspace}}/build \
    -G "Unix Makefiles" \
    -D CMAKE_INSTALL_PREFIX=${{github.workspace}}/dist/darwin/arm64 \
    -D CMAKE_VERBOSE_MAKEFILE=ON \
    -D BUILD_SHARED_LIBS=ON \
    -D BUILD_DEMO=ON

cmake --build ${{github.workspace}}/build \
    --parallel 2 \
    --config RelWithDebInfo \
    --clean-first

cmake --install ${{github.workspace}}/build --config RelWithDebInfo

**更新：**我看到此错误。
