Summary0013029: Use of SWIG fails for out-of-source builds, if the swig interface file is not placed in same directory as CMakeLists.txt
Description *simple library project (see attached minimal example)
 *SWIG is employed to create C#-Wrapper
 *SWIG interface file Hello.i is placed in subfolder swig/
 *in-source build works
 *out-of-source build does complain that it cannot find the wrapper files created by SWIG in subfolder swig/
 *it turns out, that no wrapper source files are created
 *CMAKE_SWIG_OUTDIR is undefined
 *it seems to be irrelevant, where actual source files are placed

As a workaround you can either
 *place Hello.i in the main folder (where CMakeLists.txt relies)
 *add output directory manually: set(CMAKE_SWIG_OUTDIR ${CMAKE_CURRENT_BINARY_DIR}/swig)

Steps To Reproduceuse example project (attached file)

cd build
cmake ..
make

This happens because the directory that swig tries to write its wrapper code source file does not exist. A fix is to have cmake create the file before swig is called. See issue 0013042.
