Suggestion: add debugger "Compound" support

[lp35]

Hello everyone!

Brief Issue Summary

I want to cover compound system in vscode feature here.

To point to a binary generated by cmake, one can use

"program": "${command:cmake.launchTargetPath}",

as stated in the documentation.

However when debugging multiple binaries at the same time (e.g: client/server system), it is not possible to use cmake.launchTargetPath anymore because we need to select 2 targets to compile.

This is my current launch.json, with 2 cmake targets (respectively named client and server):

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch server",
            "type": "cppdbg",
            "request": "launch",
            "program": "${config:cmake.buildDirectory}/server_debinfo",
           .
           .
           .
            ]
        },
        {
            "name": "(gdb) Launch client",
            "type": "cppdbg",
            "request": "launch",
            "program": "${config:cmake.buildDirectory}/client_debinfo",
            .
            .
            .
        }
    ],
    "compounds": [
        {
          "name": "Server/Client",
          "configurations": ["(gdb) Launch client", "(gdb) Launch server"],
        }
      ]
}

The problem is when the configuration is changed (for example, go for release) and the binaries names change, we have to go in launch.json and modify the paths to the binaries by hand each time.

Suggestion:

A nice addition to this plugin would be to have a special variable allowing to point to the binary of a given target, e.g:

"program": "${command:cmake.launchTargetPath(client)}",

and

"program": "${command:cmake.launchTargetPath(server)}",

so compound can be used very easily.

Other Notes/Information

Thank you so much for this wonderful plugin, it is really a daily pleasure to use it!

Louis-Paul Cordier (@lp35) There might be a bug with the above config:
When starting to debug the compound, there would be only the terminal of the compound shown. There should be two since two programs are running.

Yes it is a bug as the behaviour is random. Are you just reporting or are you able to do something about it?

Cheers
