Configure CMake Build Process

CMake is a third-party, open-source tool for build process management. To build code generated from MATLAB® code, the software provides CMake toolchain definitions for:

  • Microsoft® Visual C++® and MinGW® on Windows®, GCC on Linux®, and Xcode on Mac computers, using Ninja and makefile generators.

  • Microsoft Visual Studio® and Xcode project builds.

If a supported toolchain is installed on your development computer, you can specify the corresponding CMake toolchain definition during code generation. When you generate code, CMake:

  1. Uses configuration (CMakeLists.txt) files to generate standard build files.

  2. Runs the compiler and other build tools to create executable code.

You can provide custom CMake toolchain definitions by using the target package. For more information, see Create Custom CMake Toolchain Definition.

Specify CMake Toolchain Definition

Using MATLAB Coder App

In the Generate Code, step, on the More Settings > Hardware tab:

  1. Specify your hardware board and, optionally, hardware implementation parameters. This information determines the selection of toolchain definitions that is available. The default value, MATLAB Host Computer, is applicable for deploying to the computer where MATLAB is running. For more information, see Available CMake Toolchain Definitions.

  2. Specify these build process parameters:

    • Toolchain — From the drop-down list, select a CMake toolchain definition.

    • Build configuration — Select one of these values:

      • Release — Optimizations enabled.

      • Debug — Optimizations disabled, debug symbols generated.

      • RelWithDebInfo — Optimizations enabled, debug symbols generated.

      • MinSizeRel — Optimized for size, debug symbols not generated.

      • Specify — Enables you to specify toolchain details through the CMake Configure and CMake Build fields.

    • Toolchain details — If Build configuration is Specify, populate these fields:

      • CMake Configure — Additional command-line arguments to pass to CMake when generating the project build system builder artifacts for the downstream tools.

      • CMake Build — Additional command-line arguments to pass to CMake when using it in build mode.

At Command Line

In a coder.CodeConfig or coder.EmbeddedCodeConfig object:

  1. If necessary, configure the target hardware by assigning a coder.hardware object to the Hardware property or modifying the HardwareImplementation property by assigning a coder.HardwareImplementation object. This information determines the selection of toolchain definitions that is available. For more information, see Available CMake Toolchain Definitions.

  2. Specify the build process by assigning the Toolchain and the BuildConfiguration properties. If you set BuildConfiguration to 'Specify', use the CustomToolchainOptions property for customization of settings for tools in the selected toolchain. For more information on the available BuildConfiguration options, see the previous section.
