Getting Started

cmake_minimum_required(VERSION 2.8.7)
project(HelloWorld)

find_package(CMakeAll 1.2 REQUIRED)

cma_add_projects("/source/dir/ProjectA.cmake")

cma_add_projects(ProjectB ProjectC ProjectD
  PREFIX "${PROJECT_SOURCE_DIR}/"
  SUFFIX ".cmake")

cma_configure_projects()
cma_configure_launcher()
cma_print_projects()

where a simple project definition script for ProjectA may contain:

set(EP_REQUIRED_PROJECTS ProjectB)
set(EP_URL "https://github.com/organization/ProjectA.git")

cma_end_definition()

ExternalProject_Add(${EP_NAME}
  DEPENDS ${EP_REQUIRED_PROJECTS}
  GIT_REPOSITORY ${EP_URL}
  GIT_TAG v1.0
  SOURCE_DIR ${PROJECT_BINARY_DIR}/${EP_NAME}
  CMAKE_ARGS -DCMAKE_BUILD_TYPE:STRING=Relase
  BINARY_DIR ${PROJECT_BINARY_DIR}/${EP_NAME}-build
  INSTALL_COMMAND "")

Variables listed below can be used to define a project, and should be set prior to calling cma_end_definition.

set(EP_NAME "${FILENAME}")    # project name
set(EP_REQUIRED_PROJECTS "")  # list of required projects
set(EP_REQUIRED_OPTIONS "")   # list of required options
set(EP_URL)                   # URL(s) of remote location to be verified
set(EP_PATCH "")              # patch file to apply

set(EP_OPTION_NAME "${DIRNAME}_${EP_NAME}")  # project CMake option
set(EP_OPTION_DEFAULT OFF)                   # default value of option
set(EP_OPTION_DEPENDENT OFF)                 # hide option until requirements are met
set(EP_OPTION_DESCRIPTION "")                # option description
set(EP_OPTION_ADVANCED OFF)                  # mark option as advanced

Each project may define its own environment variables using cma_envvar.

cma_envvar(PATH PREPEND @BINARY_DIR@/@LIBDIR@/@INTDIR@)

# variables that expand at build-time
set(INTDIR "@INTDIR@")
set(LIBDIR "@LIBDIR@")
set(SOURCE_DIR "@SOURCE_DIR@")
set(BINARY_DIR "@BINARY_DIR@")
set(INSTALL_DIR "@INSTALL_DIR@")

which are then used to configure a launcher script that may be used as:

cmake -P /binary/dir/HelloWorld.cmake

Obtaining

Option 1. Standard method where CMake will request the path to your local copy.

find_package(CMakeAll 1.2 REQUIRED)

Option 2. Using FindCMakeAll.cmake where the project is automatically cloned from GitHub. If version number is not specified master branch is cloned and updated with each configure.

list(APPEND CMAKE_MODULE_PATH "/path/to/FindCMakeAll.cmake")
find_package(CMakeAll 1.2 REQUIRED)
