Passing Cario's dir to meson

While trying to build epiphany I received: > Run-time dependency cairo found: NO (tried pkgconfig and cmake) > meson.build:80:0: ERROR: Dependency "cairo" not found, tried pkgconfig and cmake Then I tried to pass cairo to it:PKG_CONFIG_PATH=/media/34GB/Arquivos-de-Programas-Linux/Cairo-1.10.0/lib/pkgconfig/ meson .. The error messages persisted. On another post I say someone suggesting to use setenv PKG_CONFIG_PATH=/media/34GB/Arquivos-de-Programas-Linux/Cairo-1.10.0/lib/pkgconfig/ meson .. However, setenv doesn't work on my terminal The final part of meson.log.txt: > Pkg-config binary for 1 is not cached.

Aborting. Run-time dependency cairo found: NO (tried pkgconfig and cmake) > meson.build:80:0: ERROR: Dependency "cairo" not found, tried pkgconfig and cmake I have no idea why pkg-config is not finding it. Yet, cmake is not looking into Cairo's dir, since I didn't pass anything to it. probably there is a way to so. The problem is thatit is being called indirectly by meson.
