I think the list of osgearth libraries came from maria's code, but I'm
really not sure.
The cmake code you posted here checks if the flag -Wall works in the
current compiler and adds it if it does. I thought it would only work
on gcc, though.
I think warnings should be enabled on all platflorms. If the code
generated by moc causes warnings we should either try to fix it or
silence warnings only from those files.
