'make doesn't see changes?
Scenario 1:
I checked out a project, and made some changes to a source file, and did make, and make sees the changes.
Scenario 2:
I checked out the project again to different directory (some reasons), copied the modified source file here, and did make and nothing happens, if I run the program, I don't see my changes, make doesn't see that I made change to this source file

Adding to existing answers:
To touch the targets, you can use the -t or --touch option of make. This option will not make the target but just touch it so that the next time you invoke make, the target will be made.
Alternatively you can use the -B or --always-make option which will unconditionally make the target irrespective of the modification of it's dependent(s).

okay, I just touched the copied (modified) source and now make recognizes the changes.

If you used cp to copy files options -a --archive -p --preserve will preserve the timestamp. That is not what you want!
Add option --no-preserve=timestamps
cp [options] --no-preserve=timestamps .....

Make sure you have your .PHONY tags and they are correct
