I try to generate my PyQGIS plugin documentation with Sphinx.
I made a Python virtualenv based on the QGIS environment and initiated my Sphinx doc with the package already installed in it.
But when I generate the htmlHTML doc, I get this error :
WARNING: autodoc: failed to import module 'mymodule' from module 'mainmodule'; the following exception was raised: No module named 'qgis'
How can I tell sphinxSphinx where to find QGIS?
