* Move toolchain-specific options to their own files.
* Clean up and modernize the use of toolchain options.
* Use modern cmake LTO support.
* Remove dead cmake code and cmake functions available in upstream cmake.
* Update README.md to remove references to removed build options.
Create and enable auto-updater for MacOS using `Sparkle=1.23`. We need
to sign our app using an `Apple Developer Key` for it to work properly,
since we are not going to sign updates with the Sparkle key.
Add all auto-updater files to `gettext`'s pot.
Use `str_split` to always get related stable version. We do not want
to check for nightly builds.
For Windows, we create the flag `-DHTTPS` to select between using an
HTTPS or HTTP URL for the auto-updater checks. We use this to keep
support for Windows XP (HTTP only) while all others should be HTTPS.
Also, use `::FreeLibrary` to allow us to remove the temporary file
that stores the `WinSparkle.dll`. Previously, we could not get it to
work with `wine`.
Add the -DUPDATE_APPCAST=TRUE option to invoke the UpdateAppcast.cmake
script, which clones the github pages repo and sets the version in the
appcast.xml to the last tag, presumably made with -DTAG_RELEASE.
The script prints out a final set of instructions to actually push the
change to git.
If the option -DUPDATE_APPCAST=UNDO is used, the clone is removed and no
changes are made.
Also use the correct method of splitting the tag list output into
multiple lines.
