It will provide paths, but also additional information required to bild a program
with that lib.
Here is an example:
jmayer@egg:~> pkg-config --cflags gtk+-3.0
-pthread -I/usr/include/gtk-3.0 -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/pixman-1 -I/usr/include/libpng12 -I/usr/include/libpng15
jmayer@egg:~> pkg-config --libs gtk+-3.0
-lgtk-3 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0
If linking would require -L or other flags, they would be displayed as well.

The current windows build process seems to require
set WIRESHARK_TARGET_PLATFORM=winXX
so I added
set WIRESHARK_BASE_DIR=c:/wireshark
If you think a registry entry would be better: That's supported by cmake
as well and would probably be a cleaner solution.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
