   @cmcfarlen Is this change correct? Looking at the automake, it's checking to see whether `execinfo.h` is present to set the `has_backtrace` symbol. On FreeBSD, it also checks for `libexecinfo`.
   
   I googled the make docs, and I think that this should be using [FindBacktrace](https://cmake.org/cmake/help/latest/module/FindBacktrace.html)
   ```
   FindBacktrace()
   if (Backtrace_FOUND)
     FindBacktrace
     -- do something with the output variables here
   endif()
   ```
