Subject: [PATCH] cmake: Improve FindPoDoFo

Add some rst based documentation and provide an imported target for
example.
I've dropped -DUSING_SHARED_PODOFO, which looks weird nowadays and
seems to exist because of Windows, which I can't test. So comment it out
for now, but it'll probably be removed in the future, if nobody turns up
who cares about Windows and can comment on it.

+FindPoDoFo
+------------
+
+Try to find PoDoFo, a C++ library to work with the PDF file format
+
+This will define the following variables:
+
+``PoDoFo_FOUND``
+    True if PoDoFo is available
+``PoDoFo_VERSION``
+    The version of PoDoFo
+``PoDoFo_LIBRARIES``
+    The libraries of PoDoFofor use with target_link_libraries()
+``PoDoFo_INCLUDE_DIRS``
+    The include dirs of PoDoFo for use with target_include_directories()
+
+If ``PoDoFo_FOUND`` is TRUE, it will also define the following imported
+target:
+
+``PoDoFo::PoDoFo``
+    The PoDoFo library
+
+In general we recommend using the imported target, as it is easier to use.
+Bear in mind, however, that if the target is in the link interface of an
+exported library, it must be made available by the package config file.
