The library's CMake automatically configures itself for what your system supports. The ideal configuration is as
10521052
follows:

1054-
| Platform | Unwinding | Symbols | Demangling |
1055-
| -------- | ------------- | ------------------ | -------------------- |

| MacOS | `_Unwind` | libdwarf | cxxabi.h |
1058-

Support for these back-ends is the main development focus and they should work well. If you want to use a different
10621062
back-end such as addr2line, for example, you can configure the library to do so.
