9 # Sphinx ships with a script named "sphinx-build", which is usually
10 # installed in "/usr/bin". Unfortunately, this script uses
11 # "/usr/bin/python" as its interpreter. Since "/usr/bin/python" can
12 # be either Python 2 or Python 3, depending on the distribution, and
13 # since we absolutely need the Python 3 Sphinx package for Babeltrace
14 # because it needs to import our bindings for autodocumentation,
15 # there's no way to tell if "sphinx-build" is actually using Python 2
18 # This macro checks if the Sphinx package ("sphinx") is installed
19 # and visible from the interpreter designated by the PYTHON variable.
20 # It sets PYTHON_SPHINX_EXISTS to "yes" if Sphinx is found for the
21 # given Python interpreter, otherwise "no".
