I have no other emacs installation. So I am pretty sure this is PGTK
build. Using following command to build,

--8<---------------cut here---------------start------------->8---
	    ./autogen.sh \
		&& ./configure --prefix=$HOME/.local \
			       --with-tree-sitter \
			       --with-pgtk \
			       CFLAGS='-O0 -g3' \
		&& make -j`nproc` \
		&& make install
--8<---------------cut here---------------end--------------->8---


The output of "ldd" against emacs and emacsclient from my path
are as follows,
