You probably need to add --with-static-cairo to the configure step.

And perhaps it might need some more tweaking.

The cairo-svg.h file was not included in the cairo package.

• include/cairo/cairo-features.h

I don't know why pkg-config is not finding cairo Fixed!

@anutosh491 The issue with pkg-config is that the dependencies for those packages were not being met. This is probably also what was happening with harfbuzz, maybe we should rebuild harfbuzz and move the dependencies back to the host environment.

It seems that cairo and pango need to be rebuilt before they can be integrated into r-base :(

From cairo we need cairo-png

error: call to undeclared function 'cairo_surface_write_to_png'; 

And from pango we need libpangocairo.a.
