Build System

Kindred Create uses CMake for build configuration, pixi (conda-based) for dependency management and task running, and ccache for compilation caching.

Overview

CMake >= 3.22.0
Ninja generator (via conda presets)
pixi manages all dependencies — compilers, Qt6, OpenCASCADE, Python, etc.
ccache with 4 GB max, zlib compression level 6, sloppy mode
mold linker on Linux for faster link times

CMake configuration

The root CMakeLists.txt defines:

Kindred Create version: 0.1.5 (via KINDRED_CREATE_VERSION)
FreeCAD base version: 1.0.0 (via FREECAD_VERSION)
CMake policy settings for compatibility
ccache auto-detection
Submodule dependency checks
Library setup: yaml-cpp, fmt, ICU

Version injection

The version flows from CMake to Python via configure_file():

CMakeLists.txt (KINDRED_CREATE_VERSION = "0.1.5")
    → src/Mod/Create/version.py.in (template)
    → build/*/Mod/Create/version.py (generated)
    → update_checker.py (imports VERSION)

CMake presets

Defined in CMakePresets.json:

Preset	Platform	Build type
`conda-linux-debug`	Linux	Debug
`conda-linux-release`	Linux	Release
`conda-macos-debug`	macOS	Debug
`conda-macos-release`	macOS	Release
`conda-windows-debug`	Windows	Debug
`conda-windows-release`	Windows	Release

All presets inherit from a hidden common base and a hidden conda base (Ninja generator, conda toolchain).

cMake/ helper modules

The cMake/ directory contains CMake helper macros inherited from FreeCAD:

FreeCAD_Helpers — macros for building FreeCAD modules
Platform detection modules
Dependency finding modules (Find*.cmake)

Dependencies

Core dependencies managed by pixi (from pixi.toml):

Category	Packages
Build	cmake, ninja, swig, compilers (clang/gcc)
CAD kernel	occt 7.8, coin3d, opencamlib, pythonocc-core
UI	Qt6 6.8, PySide6, pyside6
Math	eigen, numpy, scipy, sympy
Data	hdf5, vtk, smesh, ifcopenshell
Python	3.11 (< 3.12), pip, freecad-stubs

Platform-specific extras:

Linux: clang, kernel-headers, mesa, X11, libspnav
macOS: sed
Windows: pthreads-win32
