Summary: add uninstalled pc file for libgphoto

Initial Comment:

The Solaris GNOME build system builds packages that include multiple modules.  The attached patch adds an uninstalled.pc file which allows you to build against libgphoto before it is actually installed.  Could this uninstalled.pc file be added upstream?

I am using

Libs: ${pcfiledir}/libgphoto2_port/libgphoto2_port.la -lm
Cflags: -I${pcfiledir}/@srcdir@

now. In my tests,

${pc_top_builddir} evaluates to "${top_builddir}" (which is then filled by
gphoto2's Makefile with gphoto2's top_builddir instead of libgphoto2'
top_builddir)

${pcfiledir} evaluates to "/absolute/path/to/where/libgphoto2/builds",
i.e. prepending ${pc_top_builddir} (aka '${top_builddir}') does not make
any sense.

So your definition

includedir=${pc_top_builddir}/${pcfiledir}

does not work for me at all.

Does that make any sense to you?

Could you possibly test current SVN? If you want to, I can build you
tarballs of it.

The ${pc_top_builddir}/${pcfiledir} is standard for uninstalled-pc files. 
Many modules ship uninstalled-pc files and if you look at them they all
look like this.  For example, here is the one for GDK in the GTK+ module:

That libfoo-uninstalled.pc is a beautiful idea. I'll have a look at how it
can be used and then add it.

The line "includedir=${pc_top_builddir}/${pcfiledir}" looks a little
suspicious to me because I have not been aware of anybody defining
pc_top_builddir or pcfiledir variables so far.

I had been hardcoding the respective _CFLAGS and _LIBS definitions in the
gphoto-suite/configure.ac file until now.

Can this go upstream?
