From: Markus Heiser <markus.heiser@xxxxxxxxxxx>
Remove the 'DOC_NITPIC_TARGETS' from main $(srctree)/Makefile and add a
more generic way to build only a reST sub-folder.
* control *sub-folders* by environment SPHINXDIRS
* control *build-theme* by environment SPHINX_CONF
Folders with a conf.py file, matching $(srctree)/Documentation/*/conf.py
can be build and distributed *stand-alone*. E.g. to compile only the
html of 'media' and 'gpu' folder use::
make SPHINXDIRS="media gpu" htmldocs
To use an additional sphinx-build configuration (*build-theme*) set the
name of the configuration file to SPHINX_CONF. E.g. to compile only the
html of 'media' with the *nit-picking* build use::
make SPHINXDIRS=media SPHINX_CONF=conf_nitpick.py htmldocs
With this, the Documentation/conf.py is read first and updated with the
configuration values from the Documentation/media/conf_nitpick.py.
