recompile cython library

[Frank Dellaert]

add dependency on pyx

[Frank Dellaert]

@thduynguyen I hope life is good at TRI :-) Probably very busy ! But, could you possibly take a quick look at how to make sure cython properly rebuilds if the pyx is re-generated? Then we can close this issue!

Hi @dellaert, I have little time indeed, but lots of fun! Still think of you everyday though. :)

Regarding this issue, I cannot reproduce the problem. Changing one line in gtsam.h triggers the full cython rebuild for me. (Tested on Ubuntu 16.04, cmake version 3.5.1). Line 98 in GtsamCythonWrap.cmake should make that happen.

Can you help verify if this is still an issue for you? If not, can I suggest to close this issue and reopen it again (and tag me) when someone can reproduce it in the future?

Thanks!

Ah, now I remember. This happens when pyx is updated due to code changes while gtsam.h stays the same.

pull request #321 should address this issue.

Merged in thduynguyen/gtsam-duy/fix/pyx_dependency (pull request #321) close issue #354

re-cythonize if pyx file is updated.
