Status: We know it could be built last December (prior to public release), and all external dependencies have Mac support, so we should have a good idea of the missing pieces.

• Set up homebrew builds for libfunctionality and jsoncpp (if needed)
  • Potential implementation (libltdl or other) needed in libfunctionality (which is a simple wrapper for loading plugins at runtime)
• Set up homebrew build for OSVR-Core (though it won't build fully at first) - known implementation details needed:
  • usbserialenum - could just use dummy impl right now
  • plugin search path code (in PluginHost)

Quick reference examples

Using the C++14 standard library.

• Trait: std::add_pointer
  • is a "template" (has template parameters) - not a type unless evaluated.
  • Evaluate: typename std::add_pointer<int>::type (aka typepack::t_<std::add_pointer<int>>) is int *
• Alias (alias template): std::add_pointer_t
  • is a "template" (has template parameters) - not a type unless evaluated.
• application: std::add_pointer_t is int *
