pkgconfig files needed for detection in some situations

[GoogleCodeExporter]

osgAudio does not create pkgconfig files to find osgAudio when using pkg-config 
under *nix based operating systems. This can cause serious issues when using 
things such as SCONS. This is a serious issue blocking use of osgAudio in the 
project I work with due to the inability to find it using scons.

Attached are some modifications and parts that I adapted from the base OSG to 
fix the issue of osgAudio not being findable under pkgconfig. This causes 
serious issues under situations such as trying to find dependencies under SCONS 
if the pkgconfig files don't exist. This should fix it.

Note that these are very heavily based off of the base OSG contents related to 
this aspect.

Attaching a fixed version of the file, the first version had incorrect 
capitalization, which prevented Linux from seeing the libraries.

Thanks for your patch. We will review it and see if it will fit well into the 
osgAudio CMake system.

As a general comment we have used osgAudio for the past 1 year and we used 
osgAL before that without pkgconfig files and SCons. SCons is pretty flexible 
and it is pretty straight forward to setup SCons to use osgAudio without pc 
files. Anyway, I would not let the lack of pc files get in the way of using 
osgAudio or any other library.

Alright, I wasn't aware of that not being an issue. I'm still fairly new to 
SCONS myself, so I'm not sure about some of this stuff.

Attached a fixed version of the package config scripts. This will fix detection 
of OpenAL headers for OpenALPP during compiling of applications.

This change conflicts with other changes on svn trunk. I'll need your help to 
resolve it.

I've committed your changes on a branch:
https://osgaudio.googlecode.com/svn/branches/pc

You simply need to merge this branch with svn trunk. The conflicts all occur in 
CMakeLists.txt, so if you can merge your changes into the trunk version of that 
file, then post it here or email it to me, then I can do the actual merge of 
the branch onto trunk using the (conflict resolved) CMakeLists.txt that you 
send me.
