If I change all of the "zmq.hpp" #include lines to be instead "zmq.h", then I get the following errors:
{{{

So ... it seems like unless there's some standard way to get zmq.hpp then we won't be using gr-zeromq on OSX. Any ideas? Can someone send me that file? - MLD

> If I look through the tarball for zmq 3.2.4 or 4.0.4, I find only zmq.h, no zmq.hpp. From the look of it, zmq is written as mixed C/C++, and the API header is purely C (wrapped with extern "C" if included as C++). Hence, I think the CMake Find file needs to check for both zmq.hpp and zmq.h as the header, then somehow get that info into the gr-zeromq sources. - MLD
