# OVERVIEW
#
# CMake is a cross-platform open-source build system that can generate project
# files in many different formats. It can be downloaded from
# http://www.cmake.org or installed via a platform package manager.
#
# CMake-generated project formats that have been tested with this CEF binary
# distribution include:
#
# Linux:      Ninja, Unix Makefiles
# Mac OS X:   Ninja, Xcode 5+
# Windows:    Ninja, Visual Studio 2010+
#
# Ninja is a cross-platform open-source tool for running fast builds using
# pre-installed platform toolchains (GNU, clang, Xcode or MSVC). It can be
# downloaded from http://martine.github.io/ninja/ or installed via a platform
# package manager.
#
# CMAKE STRUCTURE
#
# This CEF binary distribution includes the following CMake files:
#
# CMakeLists.txt              Bootstrap that sets up the CMake environment and
#                             loads the other CMake files.
# macros.cmake                Helper macros for building a generic CEF-based
#                             application.
# libcef_dll/CMakeLists.txt   Defines the libcef_dll_wrapper target.
# cefclient/CMakeLists.txt    Defines the cefclient target.
# cefsimple/CMakeLists.txt    Defines the cefsimple target.
#
# Existing CMake projects that use this binary distribution without changing the
# directory structure can include the existing "libcef_dll/CMakeLists.txt" file
# with minimal or no changes.
#
# BUILD REQUIREMENTS
#
# The below requirements must be met to build this CEF binary distribution.
#
# - CMake version 2.8.12.2 or newer.
#
# - Linux requirements:
#   Currently supported distributions include Debian Wheezy, Ubuntu Precise, and
#   related. Newer versions will likely also work but may not have been tested.
#   Required packages include:
#     build-essential
#     libgtk2.0-dev     (required by the cefclient target only)
#     libgtkglext1-dev  (required by the cefclient target only)
#
# - Mac OS X requirements:
#   Xcode 5 or newer building on Mac OS X 10.7 (Lion) or newer. The Xcode
#   command-line tools must also be installed.
#
# - Windows requirements:
#   Visual Studio 2010 or newer building on Windows XP SP3 or newer. 64-bit
#   version of Windows 7 or newer recommended.
#
# BUILD EXAMPLES
#
# The below commands will generate project files and create a Debug build of all
# CEF targets using CMake and the platform toolchain.
#
# Start by creating and entering the CMake build output directory:
# > cd path/to/cef_binary_*
# > mkdir build && cd build

#
#   Using Ninja with Visual Studio 2013 command-line tools:
#     (this path may be different depending on your Visual Studio installation)
#     > "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\vcvars32.bat"
#     > cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Debug ..
#     > ninja cefclient cefsimple
