Fix compilation on OS X.

[NikolausDemmel]

• without this linking fails on OS X (10.9)
  • not sure if directly referencing protobuf is the right thing here, or if gazebo's pkg-config should export the protobuf flags?

[NikolausDemmel]

If directly referencing protobuf is the right thing, then I guess dependency entries in package.xml are needed.

[stonier]

Protobuf is a transitive dependency for kobuki_gazebo_plugins (i.e. it doesn't use them directly) so I expect the correct solution is that gazebo's pkgconfig should export them.

Closing this, but reopen it if you have problems getting gazebo fixed to export them correctly or some other information comes to light.

[NikolausDemmel]

Tbh, I don't care enough to research this more, sorry. I'm not using this package myself and only was helping this guy on ros answers.

I opened a ticket this ticket over at gazebo: https://bitbucket.org/osrf/gazebo/issue/1202

@NikolausDemmel thx for your contribution. You are probably right with the addition of ${GAZEBO_LIBRARIES}. Will look into this, once I have time.

[NikolausDemmel]

Thank you.

[scpeters]

Gazebo developer here; thanks for the bug report. Until we fix the pkg-config file, I believe our cmake config file exports the protobuf dependency properly, so you should be able to use find_package(gazebo) instead.

Without crawling the headers to check for sure, I dont think this is truly necessary. We've linked and run the plugin without the gazebo libraries and if you run ldd on the library it doesn't show up, so it hasn't even been accidentally included as a transitive dependency.

The headers though are necessary for include_directories.

Yeah, that will be easier if it has cmake support now. Thanks for the heads up @scpeters.

[NikolausDemmel]

@scpeters: Does 1.9.5 provide a cmake module?

When I don't link in neither gazebo nor protobuf (i.e. without this patch), I get:

[scpeters]

@NikolausDemmel yes, version 1.9.5 has a cmake configuration file.

[NikolausDemmel]

@scpeters: Ah yes; I was looking for the wrong file and earlier the find_package(gazebo) did not seem to work, now it does, thanks.

[NikolausDemmel]

I changed the PR to use find_package(gazebo). Briefly tested on OS X 10.9 and it compiles.

[jihoonl]

Works fine. Merging.

[jihoonl]

Thanks @NikolausDemmel

[NikolausDemmel]

Thank you.
