Summary:                    SWIG_ADD_MODULE does not create sub directory
Description: 
When using SWIG_ADD_MODULE to create wrappers, passing the input file from a sub
directory there will be an error when trying to build since swig tries to write
it's output to a directory that does not exist.



Steps to Reproduce: 
The example works fine:
SWIG_ADD_MODULE(example python example.i example.cxx)

This does not work (the input is in a subdirectory):
SWIG_ADD_MODULE(example python subdir/example.i subdir/example.cxx)

This will result in the following error (since SWIG tries to write it's ouput
file to a non-existing directory under the build dir)

Unable to open file ****/build/subdir/examplePYTHON_wrap.c: No such file or
directory

This can be fixed by manually creating the directory:
file(MAKE_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/subdir)

This is not obvious or mentioned in the documentation. SWIG_ADD_MODULE should
create the directory it's trying to output to.
