Makefiles regenerate output files at every build even when no modifications #31
Description
I don't know if Makefiles allow this but it could be worth checking.
____ What steps will reproduce the problem?
1. Generate your makefiles through Make-it-So
2. Build your app on Linux
3. Change something in a project which depends on an already generated
library/exe project, and launch make again.
____ What is the expected output?
When building a project, I don't expect Make to actually rebuild every library
(previously generated by Make-it-So) my project depends on.
In my case: I have an app which depends on 1 exe and 2 libraries, which
themselves depend on 5 other libraries, and so on. And everytime I do a make on
my app, the "ar rcs" part is called which can be long with large libraries.
Someone should check if there's some way to indicate in the Makefile not to
execute this part if nothing has changed since the last build.
