Python bindings issue when building with static libraries

[agarny]

I am on macOS and I have everything set up to build Python bindings and it all works as expected if I do:

mkdir build
cd build
cmake -G Ninja ..
ninja

However, if I ask for a static version of libCellML to be built then I am getting various linking issues:

mkdir build
cd build
cmake -G Ninja .. -DBUILD_SHARED=OFF
ninja
...

It doesn't make sense to build the python bindings with a static libCellML library. I'm not sure on this but Windows in the past hasn't been a fan of allocating from one dll and deallocating from another.

Then, shouldn't we have one of those Configuration confusion messages like we have?

Also, FWIW, libOpenCOR's Python bindings are built off a static version of libOpenCOR. :)
