Changes from Ziras

several cross-platform and packaging fixes

  • add “lrelease” to src.pro CONFIG, so it doesn’t have to be invoked
    manually, helping packagers to use their standard qmake-based rules
  • add hardcoded version string to src.pro which is used when building from
    a release archive instead of a git repo (which is normal when building
    packages)
  • add fallbacks for unknown operating systems and processor
    architectures, assume unknown operating systems are POSIX compliant
  • add explicit support for FreeBSD

fix some build / install issues

  • on non-windows platforms, enable a default PREFIX of / usr / local
  • move documentation files to $ PREFIX / share / doc
  • fix lrelease issue, work around https://bugreports.qt.io/browse/QTBUG-77398
    by adding explicit install commands for the .qm files
