# Typewriter - lightweight text editor
# Requires: SDL2, SDL2_ttf
#
#   make              dynamic build against the system SDL2 / SDL2_ttf (default)
#   make STATIC=1     self-contained executable: SDL2, SDL2_ttf and FreeType are
#                     linked in, nothing besides the OS is needed at runtime.
#       Windows       links the MSYS2 static libs
#                     (pacman -S mingw-w64-x86_64-SDL2 mingw-w64-x86_64-SDL2_ttf)
#       Linux/macOS   run `make deps` (or scripts/build-deps.sh) once first; it
#                     builds static SDL2 + SDL2_ttf into deps/prefix
#   make embed-font   regenerate font_embed.h after replacing typewriter.ttf
