This repository contains toolchains usable for crosscompiling with CMake. They're tailored for and mainly used by Magnum but should work for other projects as well.
Assuming a CMake project, point CMAKE_TOOLCHAIN_FILE to one of the toolchain
files during the initial CMake invocation. While relative paths may work in
certain cases, it's better to always pass an absolute path. The
CMAKE_TOOLCHAIN_FILE variable is only used by CMake during the initial run,
it's ignored (and thus doesn't even need to be specified) in subsequent runs.
mkdir build-emscripten && cd build-emscripten
cmake .. -DCMAKE_TOOLCHAIN_FILE=path/to/toolchains/generic/Emscripten-wasm.cmake
The toolchain file then sets up other paths (such as pointing
CMAKE_MODULE_PATH to the modules/Platform/ directory) and the process will
result in a configured build directory that can be subsequently used as any
other. See comments in particular toolchain files for platform-specific
details.
