Osvr external project

[DuFF14]

Stuck on trying to get past this error: https://gist.github.com/DuFF14/e40e07deb07988f062c4#file-gistfile1-txt-L308

Tried this solution but no luck: http://stackoverflow.com/questions/12179154/undefined-reference-to-boostprogram-optionsoptions-descriptionm-default-l

Also concerned about this line here: https://gist.github.com/DuFF14/e40e07deb07988f062c4#file-gistfile1-txt-L148
If I add a JSONCPP_LIBRARY arg with a path to the directory it installs to, this notification disappears, but the error on line 136 remains (Local JSONCPP submodule not found. To download with Git, run git submodule update --init)

The "local jsoncpp submodule not found" is just a warning that VRPN itself won't have json support - that happens on PC too, and is not a problem.

I am getting a "reference is not a tree" on the osvr-core submodule (I think): did you make a commit in one of the submodules without pushing it? (You have to commit and push the submodule itself, since it's a git repo, as well as commit and push the currently-active tree for that submodule in superproject)

And the boost error looks like it's trying to link against your host/native version of boost (Mac) rather than the android version - I bet you tripped on one of the "find_host_package" bad-advices out there on the internets. (That works for people using header-only Boost libraries since there's no difference between the headers on the different platforms - they're not actually getting the "boost for android" they tried to build - but is flawed at the conceptual level)

This line and ones like it only make sense if you are providing multiple options - it serves to populate the dropdown in the CMake GUI.

Closing in favor of branch with fixed email.
