Refactor includes #7
Conversation
This is required to allow other projects to include files from libff without explicitly putting the root of libff source into their include path.

@tromer, that is a valid point. I'm not entirely convinced that this is worse than the current situation, however --- as mentioned in the pull request, any project that has a file named "common/utils.hpp" effectively cannot use libff. Do you have suggestions for how to resolve both of these issues? |

@popoffka above refers to a comment I accidentally deleted. Original text:

Suggested alternative: move all include files into corresponding "namespace" directories, and then use etc. This keeps directory namespaces clean, and consistent regardless of which subdirectory or project you're in. |
|
Checking best practice empirically on So it seems like both options are in wide use. But looking at the actual projects, I see that "reputable" libraries like boost, Qt, opencv2, gtest, gstreamer, gnuradio, NTL all use directory-qualified includes. Exceptions include photon and some KDE libraries. So my tendency is still towards explicit directories. |

Okay, I will convert all includes to be absolute and use explicit directory names and submit new pull requests. Thanks! |

This pull request converts the paths in all local includes (i.e. those including files from within libff) from absolute to relative. Using absolute paths in local includes is suboptimal, because it means that any project trying to include a file from libff must also include libff's src directory in its include path.
In other words, for
#include "common/utils.hpp"to work inside a libff file, it will also have to work inside the files of the project that's trying to include libff, which might lead to ambiguities if that project also has acommon/utils.hppfile, which is not unreasonable.External projects should add
/usr/include(or wherever libff was installed) to their include paths, and then include libff as#include <libff/algebra/whatever>. Pull requests that implement this in libsnark and libfqfft will be submitted in a couple of minutes.This pull request (as well as the accompanying ones in libsnark and libfqfft) was largely generated using a Python script.
