| # HandleLibcxxFlags - A set of macros used to setup the flags used to compile |
| # and link libc++abi. These macros add flags to the following CMake variables. |
| # - LIBUNWIND_COMPILE_FLAGS: flags used to compile libunwind |
| # - LIBUNWIND_LINK_FLAGS: flags used to link libunwind |
| # - LIBUNWIND_LIBRARIES: libraries to link libunwind to. |
