>Description:
fonts/harfbuzz without introspection option causes error for make in devel/pango 
>How-To-Repeat:
first build and install fonts/harfbuzz with
PKG_OPTIONS.harfbuzz=-introspection in mk.conf followed by make
in devel/pango. This results in:

Couldn't find include 'HarfBuzz-0.0.gir' (search path: '['/usr/pkg/share/gir-1.0', '/usr/pkg/share', 'gir-1.0', '/usr/local/share/gir-1.0', '/usr/share/gir-1.0', '/usr/pkg/share/gir-1.0', '/usr/share/gir-1.0']')
ninja: build stopped: subcommand failed.
*** Error code 1

Stop.
make[1]: stopped in /usr/pkgsrc/devel/pango
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/devel/pango


>Fix:
Currently devel/pango has 
MESON_ARGS+=            -Dintrospection=enabled
in the Makefile. Fix could be to use -Dintrospection=disabled
when PKG_OPTIONS.harfbuzz has -introspection.
