Defining a function or macro with named arguments

The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-07/recipe-04 and has a C++ example. The recipe is valid with CMake version 3.5 (and higher) and has been tested on GNU/Linux, macOS, and Windows.

In the previous recipes, we explored functions and macros and used positional arguments. In this recipe, we will define a function with named arguments. We will enhance the example from Recipe 1, Code reuse with functions and macros and instead of defining tests using the following:

add_catch_test(short 1.5)

We will be able to call the following:

add_catch_test(
  NAME
    short
  LABELS
    short
    cpp_test
  COST
    1.5
  )
