Cmake failed to build ELL's Python language bindings #175

Hi, I am following the instructions to the letter and was able to successfully build ELL. I do see all the project executable in ELL/build/bin. But, when I try to build python binding using; cmake --build . --target _ELL_python --config Release --> fails

Can you please help to troubleshoot the issue?

Thank You

Can you make sure you ran "build.cmd" ? This will populate your externals folder which contains nuget packages, including one for SWIG, so you should see this:

(ell) d:\git\ELL\ELL\external>dir /s /b swig.swg
d:\git\ELL\ELL\external\swigwintools.3.0.12\tools\swigwin-3.0.12\Lib\swig.swg

The issue was that SWIG_LIB in all build files are pointing to swig root directory instead of \Lib directory. I change the path to \Lib and solved the problem.
