How to do it

We will reuse hello-world.cpp and CMakeLists.txt from the previous recipe. The only difference is in the invocation of CMake, since we will now have to pass the generator explicitly with the -G CLI switch.

1. First, we configure the project using the following:

$ mkdir -p build
$ cd build
$ cmake -G Ninja ..

-- The CXX compiler identification is GNU 8.1.0
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- Configuring done
-- Generating done
-- Build files have been written to: /home/user/cmake-cookbook/chapter-01/recipe-02/cxx-example/build

2. In the second step, we build the project:

$ cmake --build .
