A CMake compiler to help building Ports/NIFs in your Elixir/mix project.

Add elixir_cmake to your list of dependencies in mix.exs:

defdepsdo[{:elixir_cmake,"~> 0.7.0"}]end

Add :cmake to your compilers in mix.exs:

defprojectdo[# ...compilers: [:cmake]++Mix.compilers(),# ...]end

Create your CMakeLists.txt in the root of your project or specify the path to an existing CMakeLists.txt file in your project config.

defprojectdo[# ...cmake_lists: "path/to/CMakeLists.txt",# ...]end

The source files can reside anywhere the CMakeLists.txt file has access to.

You will need to copy the contents to your priv directory by either specifying a compile alias or by directing the binary output to priv/ in your CMakeLists.txt. file.

In this example we specify a project namedEXAMPLE, with source files in src/:

cmake_minimum_required(VERSION 3.0) project(EXAMPLE) set(CMAKE_RUNTIME_OUTPUT_DIRECTORY${CMAKE_SOURCE_DIR}/priv) file(GLOB EXAMPLE_SRC src/*.c) SET (CMAKE_C_FLAGS "-g -O3 -pedantic -Wall -Wextra -Wno-unused-parameter -std=c99") include_directories(SYSTEM) add_executable(example ${EXAMPLE_SRC})

Run mix compile (or mix compile.cmake for just the CMake build) and you should find a compiled binary in priv/ afterwards.

Be sure to read the documentation too.
