This is a clone of the (silly) PadLeft library -- but the CMakeLists.txt file seems to be empty!

Your task is to re-write CMakeLists.txt for this project.

Your CMake project definition should consist of two targets:

1. A library target named padleft with the source file src/padleft.cpp. The public headers for this library live in the include/ directory

2. An executable target named test_padleft, using the source files test/test_padleft.cpp and test/catch_main.cpp. This target should link with the padleft target

Your project definition should also require a minimum CMake version of 3.1, and that it uses the C++ language (only).

Have fun!
