# Expected variables:

# - options: dictionary "option-name" : "description"

# if there's '=' in option name, it expects an argument. Otherwise it's boolean.

# - alias: optional, you can make shortcuts to longer named options. Remember to use = in target name.

|

# - preprocess: run before command-line arguments ($argv) are reviewed
|

# - postprocess: run after options are reviewed and all data filled in
|

# Available variables in postprocess:
|

# - optval (array): contains all option names with their assigned values
|

# - cmakeopt (scalar): a list of all options for "cmake" command line
