if i remember, you can pass pkg-config path in command line
(no need for env var).. this is what i was using , if i remember:

CMWin32Cairo>>#build
    gen
        puts:
'
add_custom_command(OUTPUT "${libcairoInstalled}"
    COMMAND ./configure --prefix=''${installPrefix}''
PKG_CONFIG="${pkgconfigPath}"
        PKG_CONFIG_PATH="${installPrefix}/lib/pkgconfig" CFLAGS="-m32
-march=pentium4 -I${installPrefix}/include" LDFLAGS="-m32 -march=pentium4
-L${installPrefix}/lib"
        --disable-silent-rules --disable-xlib --disable-dependency-tracking

so the question is to verify that ${pkgconfigPath} variable is properly set
(and not ignored by configure/cairo makefile.. well it shouldn't since it
worked before)

You can do

yourBuildDir> make VERBOSE=1 cairo

to see all output
