14 # This macro checks for Python and tries to get the include path to
15 # 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output
17 # $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
19 # You can search for some particular version of Python by passing a
21 # note that you *have* to pass also an operator along with the version to
23 # version number. Don't use "PYTHON_VERSION" for this: that environment
24 # variable is declared as precious and thus reserved for the end-user.
26 # This macro should work for all versions of Python >= 2.1.0. As an end
27 # user, you can disable the check for the python version by setting the
