WARNING: If you plan to use the dynamic library libopenblas_armv8-r0.3.20.dylib, you must run:

"make PREFIX=/your_installation_path/ install".

(or set PREFIX in Makefile.rule and run make install.
If you want to move the .dylib to a new location later, make sure you change
the internal name of the dylib with:

install_name_tool -id /new/absolute/path/to/libopenblas_armv8-r0.3.20.dylib libopenblas_armv8-r0.3.20.dylib

To install the library, you can run "make PREFIX=/path/to/your/installation install".

## Build with Ninja Generator
``` bash
mkdir -p build && cd build
cmake -GNinja -DCMAKE_INSTALL_PREFIX=../dist ..
cmake --build . --target install
```

执行之后会在`./dist/bin` 中生成可执行的工具
