cmake_minimum_required(VERSION 2.8.9)

project (hello)

add_executable(hello helloworld.cpp)

The CMakeLists.txt file in Listing 2 consists of only three lines:

• The first line sets the minimum version of CMake for this project, which is major version 2, minor version 8, and patch version 9 in this example. This version is somewhat arbitrary in this example, but providing a version number allows for future support for your build environment. Therefore, you should use the current version of CMake on your system, which for this example is determined just below.
• The second line is the project() command that sets the project name.
• The third line is the add_executable() command, which requests that an executable is to be built using the helloworld.cpp source file. The first argument to the add_executable() function is the name of the executable to be built, and the second argument is the source file from which to build the executable.

Are CMAKE_SOURCE_DIR and PROJECT_SOURCE_DIR the same in CMake?

PROJECT_SOURCE_DIR 

contains the full path to the root of your project source directory, i.e. to the nearest directory where CMakeLists.txt contains the PROJECT() command

CMAKE_SOURCE_DIR 

this is the directory which contains the top-level CMakeLists.txt, i.e. the top level source directory
