Make sysrepo dependency optional

This project is useful as a standalone NETCONF client, too. Do not
require sysrepo unconditionally. If not available, just build the main
NETCONF client (and a `yang-cli`, too, because it's essentially free).

The CMake setup is a wee bit complex. CMake's OPTION statement doesn't
really support tri-state dependencies, and I like automagic stuff:

- OFF for disabling stuff unconditionally, even if the deps are there,
- ON for enabling stuff, and failing if it cannot be built,
- AUTO for trying to enable stuff if possible, and gracefully disabling
  it if not available

Of course this has a potential of introducing nasty surprises to the CI,
so make sure the CI fails if the sysrepo backend gets disabled for some
reason.

Console interface to NETCONF servers

This program provides an interactive console for working with YANG data. It can connect to NETCONF servers, and also talk to sysrepo locally.

Installation

For building, one needs:

  • A C++17 compiler
  • Boost version 1.69
  • cmake for managing the build
  • libyang for working with YANG models
  • libnetconf2 for connecting to NETCONF servers
  • sysrepo version 1.4.x for the local sysrepo backend, and for the comprehensive test suite
  • replxx which provides interactive line prompts
  • docopt for CLI option parsing
  • pkg-config for building
  • Doctest as a C++ unit test framework
  • trompeloeil for mock objects in C++

Use an exact commit of any dependencies as specified in submodules/dependencies/*.

The build process uses CMake. A quick-and-dirty build with no fancy options can be as simple as mkdir build && cd build && cmake .. && make && make install.
