#
# CMake script to automatically generate the enums in script_window.hpp
#
# The file is scanned for @enum tokens, and the placeholder is filled with an enum from a different file.
#
# Example:
# // @enum enumname filename@placeholder@
# ... content here is replaced ...
# // @endenum
#
# The parameter "enumname" specifies the enumeration to extract. This can also be a regular expression.
# The parameter "filename" specifies the relative path to the file, where the enumeration is extracted from. This can also be a glob expression.
