# Hello CMake
Shows a very basic hello world example.
## New Concepts
### Minimum CMake version
```cmake
cmake_minimum_required(VERSION 2.6)
```
When creating a project using CMake, you can specify the minimum version of CMake that is supported.
### Projects
```cmake
project (hello_cmake)
```
A CMake build can include a project name to make referencing certain variables when using multiple projects.
### Creating an executable
```cmake
add_executable(hello_cmake main.cpp)
```
The add_executable() command specifies that an executable should be build from the specified source files, in this example main.cpp. 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.
HINT: A shorthand that some people use is to have the project name and executable name the same. This allows you to specify the CMakeLists.txt as follows,
```cmake
cmake_minimum_required(VERSION 2.6)
project (hello_cmake)
add_executable(${PROJECT_NAME} main.cpp)
```
In this example, the project() function, will create a variable ${PROJECT_NAME} with the value hello_cmake. This can then be passed to the add_executable() function to output a 'hello_cmake' executable.
## Building the example
```bash
$ mkdir build
$ cd build
$ cmake ..
