[CMake] Question about list ordering

[Eric Doenges]

The list <https://cmake.org/cmake/help/latest/command/list.html> command 
is what you want. Specifically, list(GET ...) will return the index of a 
string in the list, and list(INSERT ...) and list(REMOVE_ITEM ...) or 
list(REMOVE_AT ...) to insert and remove items.
