Except: that argument is not valid in this case. Neither file(GLOB nor
install(DIRECTORY will "rerun" anything if a new header file is added into
the directory...

File(GLOB is discouraged for specifying source files to add_library and
add_executable because of the "cmake won't rerun if you add a file" problem.
But in this case... it's 6 of one half dozen of the other -- neither case
will detect the addition of a header file to the system....
