A simple modern CMake project.

I wrote this project, because I have trouble to include only Header directories.
I hope this helps other people to work with CMake.

• this project contains a subdirectory with two header files

The directory tree is:

CMakeTest
    |
    |  - main.cpp
    |  - CMakeLists.txt
    |  - README.md
    |
    |  - Container
    |     | - ContainerOne.hpp
    |     | - ContainerTwo.hpp
    |     | - CMakeLists.txt
    |
    |  - tests
    |     | - test.cpp
    |
    |  - cmake-build-debug
          | - some files that cmake creates..
