You can try to add --wrap-mode=nodownload to meson options in cario.sh

meson setup build \
	--cross-file "$CROSS_FILE" \
	--wrap-mode=nodownload \
	--default-library=static \
	--buildtype=release \
	-Dprefix=/ \
	-Dfreetype=enabled \
	-Dpng=enabled \
	-Dfontconfig=disabled \
	-Dxcb=disabled \
	-Dxlib=disabled \
	-Dxlib-xcb=disabled \
	-Dzlib=disabled \
	-Dtests=disabled \
	-Dlzo=disabled \
	-Dgtk2-utils=disabled \
	-Dglib=disabled \
	-Dspectre=disabled \
	-Dsymbol-lookup=disabled \
	-Dgtk_doc=false

so it doesn't try to use subprojects.

And not sure if full log is possible?

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Even more ugly but hopefully working now (previously pkg-config was finding system libraries even though our compiled libraries were used).
