libfov cannot built out-of-tree

[GoogleCodeExporter]

libfov cannot be build from outside the source tree, because the library is 
looked for in srcdir (instead of builddir) when linking `tests` and `examples`. 
Doxygen also has issues.

I have attached a patch.

Note: docs/Doxyfile must be moved to docs/Doxyfile.in before applying.
