vcpkg-compatible package manager with C++ project scaffolding

kmpkg

A Python reimplementation of the vcpkg package manager, with built-in C++ project scaffolding via kmcmake templates.

Installation

pip install kmpkg

Requires Python >= 3.8 and cmake on PATH.

Quick Start

# Create a C++ project from kmcmake template
kmpkg new --project --name myapp -o ./myapp

# Install a port
kmpkg install fmt

# Search available ports
kmpkg search fmt

# List installed ports
kmpkg list

Configuration

kmpkg reads kmpkg-configuration.json from the current directory or kmpkg root:

{
  "default-registry": {
    "kind": "git",
    "baseline": "d5c94a00e9d3d27a88399368d789971bc7e4fca8",
    "repository": "https://github.com/kumose/kmpkgcore.git"
  }
}

The root directory defaults to $KMPKG_ROOT or /home/jeff/kmpkgcore.
