See demos/api/README.txt : basically, you need to either explicitly build the shared Gmsh libraries (cmake -DENABLE_BUILD_SHARED=1 ..; make), or the dynamic Gmsh app, which will build the shared libraries (cmake -DENABLE_BUILD_DYNAMIC=1 ..; make). Building the dynamic app is probably the most convenient, as you will get both the app and the libs. Note that both the main libgmsh and the small C wrapper libgmshc will be built automatically.

Then you need to install the libraries with "make install". Currently this will also install a copy of libgmshc in the gmsh/api directory, so that you can use it directly with the Python module. We will definitely improve the installation process later.

No, but it should be reserved for internal Gmsh (and related projects) development. You can build this internal developer API and the related bindings (these are generated by swig) with -DENABLE_INTERNAL_DEVELOPER_API=1. But I don't recommend it unless you really need them: they are unsupported and undocumented. Gmsh packagers (e.g. Debian) will also be notified that they should not ship this internal development API.
