That is correct for the language grammar libraries, but not for the
tree-sitter library itself.  Emacs can be built either with or without
the tree-sitter library, just like we do with libpng and other
optional image libraries.

If Emacs was build with the tree-sitter library, then it will attempt
to load the language grammar libraries (whcih are separate libraries)
dynamically when the corresponding language mode is activated.
