This new find module will replace the old logic used to locate a native copy of libserialport. THe old code didn't work on macOS, and was pretty messy.
While this might work when using bundled libraries, this breaks with system libraries as they are all compiled for arm64. Also, why would you need to compile an x86_64 version on arm64, and vise versa.
CMake interpreted `argtable3` to mean add `-largtable3` rather than to use the imported argtable3 target. This worked when using the bundled library, but broke with native libraries.

| Finds the sigrok serial port library (``libserialport``) |
There was a problem hiding this comment.
Tying it to sigrok seems super weird.
It's not like this library is optional, IIRC. You either have it correctly installed or you don't, so adding layers to go hunt for it seems a distraction.

- Agree, wasn't sure if there were any other libserialport libraries since it felt like a pretty common name.
- I don't really get what you're trying to say. In CMake, using a find script is the normal way to link to other libraries. With a find script, standard errors are given when the library isn't found, the call site is much cleaner, and this script can be reused in other projects.

Building on macOS with native libraries was super broken. This PR fixes dependency location for both
argtable3andlibserialport, adding aFindLibserialportCMake module to help. This PR also disables building a x86_64 and arm64 version of blisp by default on macOS, as the cross compiled binary wouldn't be able to link with native libraries.
