vcpkg new CLI command for new project initiation

[patrolez]

CLI as Command-line interface, not Common Language Infrastructure.

Is your feature request related to a problem? Please describe.
I'm always frustrated when ... I have to every time create minimal "Hello World!" grade project with just CMakeLists.txt with basic filesystem organization and adjustments to make it working with vcpkg.

While using dotnet CLI I am glad to have dotnet new opportunity. (link)
While using cargo CLI for Rust language experience I can use cargo new. (link)
While using npm CLI I can use npm init. (link)
While using angular CLI I can use ng new. (link)
I am not using conan, but seems like there exists conan new. (link)

Proposed solution
vcpkg new based on dotnet new architectural principles (including template system).

Describe alternatives you've considered
Nothing exists regarding C++. I can only rely on some repositories called like "project template" or "minimal project template": https://github.com/search?o=desc&q=cmake+project+template&s=stars&type=Repositories

https://vcpkg.readthedocs.io/en/latest/specifications/manifests/ could contain prepacked archives to bootstrap a project immediately after download-unpack-rename.

https://vcpkg.readthedocs.io/en/latest/examples/installing-and-using-packages/#cmake could contain prepacked archives to bootstrap a project immediately after download-unpack-rename.

Additional context

• Personally I think it would work better with manifest way of working regarding vcpkg.
• If project template system would be a huge thing, so I think that development could be divided for some basic system and more generic one.
• Parametrized project templates could be nice thing for example to providing C++ language version.
  • parametrization also could take into account MSBuild, CMake and provide some way to implement another integrations by contributions.
  • parametrization also might take into account the most popular Version control systems and/or vcpkg as submodule initiated project

Have you explored vcpkg create <pkg> <url> [archivename] create a new package?

Neither https://vcpkg.readthedocs.io/en/latest/specifications/manifests/, nor https://vcpkg.readthedocs.io/en/latest/examples/installing-and-using-packages/#cmake indicates that it can be done this way.

I have tried to use that, but only new directory appeared in vcpkg/ports/ which is not usable in terms of what I have had on my mind by introducing this topic.

vcpkg create it made for different purposes: https://vcpkg.readthedocs.io/en/latest/examples/packaging-zipfiles/

As I understood docs linked above, this command allows you to use some bunch of code as a vcpkg library which is not already maintained as a library available under vcpkg search.

Hello. As @strega-nil was assigned I discovered a repo https://github.com/strega-nil/vcpkg-example which is the thing I was thinking about to be "generated" on anyone's local machine after using command like:
vcpkg new --feature-flags=binarycaching,manifests --vcpkg-resolve-deps bin-hello-world-fmt-git-example --ci-githubworkflow --cmake vcpkg-example.

Where I assumed that:
❶ --feature-flags=binarycaching,manifests --vcpkg-resolve-deps would be some options passed and interpreted by vcpkg;
❷ bin-hello-world-fmt-git-example would be a name for a project template followed by parameters passed to a project template generator (customizable by project template maintainer, in this case flavor with git, fmt and binary executable target);
❸ vcpkg-example would be a name for final cmake@vcpkg@git@C++ project and the first executable target linked to src/main.cpp OR src/main.cxx under directory with the same name by default (or possibly changed by some option passed in ❶ CLI section).

@patrolez yeah, I like this! Would you be interested in working on it?
