I inserted a printout of ARGC, ARGV, and ARGN.
The resulting output is below, and below that is the result of using the flags you suggested. It appears that vtk_detect_library_type is recognizing the existence of three arguments. It recognizes PATH as one of the arguments. VIM automatically gives it special font as if it is a recognized keyword or something similar. I also don’t know if keywords or reserved words are treated as arguments under normal conditions. Then there is the inclusion of
""
"PATH"
""
cmake_parse_arguments. I recognize that the idea is that “_PATH” will be added to the base name of some variable to create a new variable name, but many of the examples I have found online have structured that process a bit differently and often include the use of set().
