How to build a CMake project using Cheerp

CMake projects can be compiled with Cheerp by passing a single additional command-line flag to cmake.

A CMake toolchain file is provided at $CHEERP/share/cmake/Modules/CheerpToolchain.cmake, where the CHEERP environment variable is set to the path of your Cheerp installation.

For example:

  • On Linux: export CHEERP=/opt/cheerp
  • On macOS: export CHEERP=/Applications/cheerp
  • On Windows: set CHEERP=C:\cheerp

Then pass the toolchain file when configuring the project.

Terminal window
cmake -DCMAKE_TOOLCHAIN_FILE=$CHEERP/share/cmake/Modules/CheerpToolchain.cmake .

Compiling to WebAssembly

To compile with -target cheerp-wasm, use CheerpWasmToolchain.cmake.

Terminal window
cmake -DCMAKE_TOOLCHAIN_FILE=$CHEERP/share/cmake/Modules/CheerpWasmToolchain.cmake .

Example

See this example repository for a working example.
