Summary
Aer has not used Cython at all since late 2020 (see #1014), and there
were still a few minor comment references to it in the code. This also
removes two CMake files that were used during the Cython build process,
but are no longer needed, except for a trivial variable that was only
used in
FindPybind11.cmake
, and is now calculated there.Details and comments
This is just bookkeeping - mostly just deleting old CMake files we're not using. At the time of making this commit, it looks like all the rest of the files in
/cmake
are used in build processes in some form. It was on my mind because Qiskit/qiskit#1439 scrubs some public references to Cython, and I was interested enough to have a check through the old history to see how Aer used to use it.
