About

mcu.cmake is a CMake library/toolchain helping with integrating the chip vendors SDKs into your CMake-based builds.

Goals and considerations

• Make microcontroller projects look and feel as much as possible as any other c/c++ project.
• Use as much as possible of the chip vendor's SDK without requiring any changes to the SDK code.
• Make the CMake code as uniform as feasible between platforms, but allow for platform-specific options and features.

Recommended layout

For single target builds:

• A top-level CMake file for your project that sets the current target.

• A copy of mcu.cmake under the project directory

• A single build directory

  /CMakeLists.txt /mcu.cmake/ /build/

To build the project the developers would execute something like this:

git clone --recursive
mkdir build
cd build
cmake ..

For builds that can build for different targets:

• A top-level CMake file with all general rules

• A copy of mcu.cmake under the project directory

• A per-configuration settings file that is used when creating the build directory

• A build directory per configuration

  /CMakeLists.txt /mcu.cmake/ /target-a.cmake /target-b.cmake /build-a /build-b

To build the project the developers would execute something like this:

git clone --recursive
mkdir build
cd build
cmake -C ../target-a.cmake ..
