Several times I have seen documentation that makes statements like "set the XXX variable to YYY", but I am not at all sure how/where these "variables" get set. Sometimes it looks like they may be old-style DOS environment variables (which I know how to set), but other times not.
So for example, looking at this SO question, the accepted answer states "NDK_MODULE_PATH must be in your path" - would that mean the DOS-environment-path? Or some other path? And in this document, it says "When you compile, you need to set the NDK_MODULE_PATH variable to the directory above...". What kind of "variable" is that? A DOS-environment variable? Some other kind? How/where would I set it?
EDIT: Just a thought - if I go to Window > Preferences > C/C++ > Build > Build Variables, I see I can add things there - do you think that's what was meant in the two examples?
