[osg-users] problem compiling OSG2.4 on MinGW

FWIW:

Not having looked at the actual CMake code for a while, I believe the 
first place that is checked is a directory called "3rdParty" parallel to 
the OSG source directory. So if you have:

.../somepath/3rdParty
.../somepath/OpenSceneGraph
.../somepath/OpenSceneGraph/src

the dependencies will be taken from that 3rdParty dir first. If not, 
then there are a few fallbacks. Those cases (OSG_LIB_PATH and C:\Program 
Files\OpenSceneGraph) are fallbacks. Perhaps these fallbacks can find 
the wrong versions of libraries, but so can the first check above. I 
think that as developers, we can be expected to check what the software 
we compile links to and make sure it links to the right things.

The only way to make sure CMake only gets the right libs is to specify 
them all manually. I don't think that's a good solution, so we're left 
with solutions that could potentially pick up the wrong versions, but if 
you've set things up correctly, will pick them all up automatically.
