CMake compiler for Mix

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

Installation

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

def deps do
  [
    {:elixir_cmake, "~> 0.1.0"}
  ]
end

Add :cmake to your compilers in mix.exs:

def project do
  [
    # ...
    compilers: [:cmake] ++ Mix.compilers(),
    # ...
  ]
end

Basic Usage

CMakeLists.txt

Create your CMakeLists.txt in the root of your project. The source files can reside anywhere the CMakeLists.txt file has access to. Direct the binary output to priv/. A project named EXAMPLE, 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.
