[Therion] macOS installation

[Oliver Legg]

Anže,

I managed to compile therion from source yesterday, on an Apple Silicon Mac, but with the previous version of macOS Sequoia 15.6.1.

I used the v6.3.4 tag (17059ab27ce491f1edac150da2b7e2011f79b800).

Are you using the CMake build method?

I did install the dependencies via Homebrew (taken from the `ladislavb/homebrew-therion` repository):

    brew install BWidget cmake catch2 fmt freetype ghostscript imagemagick lcdf libjpeg libpng pkg proj tcl vtk wxwidgets zlib
    brew install --cask xquartz
