generated swig files should be placed in build director

[Johan Hake]

Working with git and branches forces me to regenerate the SWIG interface each time I switch between two branches with diverging SWIG interface.

If the generated SWIG files could be placed in the build directory instead for into the source tree we would avoid this.

It would also be nice if we could create a CMake target for the generation of the SWIG files, so everything could be automagically handled by CMake

[Martin Sandve Alnæs]

Yes please. The build system should automate generation of all files needed to build, and all generated files should be placed in the build folder.

[Anders Logg (Chalmers)]

Yes! This would be very welcome!

[Johan Hake]

It is on its way. Probably later this week.
