How to Compile an Unreal Project (Novice Question)

This is probably a very novice question, but when I make changes to my unreal project source code and I hit ‘Compile’ in the unreal editor everything works correctly and the changes take effect the next time I hit ‘Run’. However, if I am on the command line and I navigate to my projects root and use the ‘make’ command, the changes do not seem to take effect the next time I hit ‘Run’ in the unreal editor. The following is the output when I execute the ‘make’ command

I thought that since the was a Makefile in the root directory you simply had to execute ‘make’ to compile the project. Am I missing something?
