class_docstr: Compiles everything when `python setup.py build` is run using cmake.
  
  Custom args can be passed to cmake by specifying the `CMAKE_ARGS`
  environment variable.
  
  The number of CPUs used by `make` can be specified by passing `-j<ncpus>`
  to `setup.py build`.  By default all CPUs are used.
