Make File depends upon another Make File

[Jason Todd Slack-Moehrle]

HI All,

I am converting a large project that is XCode and VS based to make  
files. I have been away from make files for a very long time.

Is it possible to have a make file depend upon another make file?

Say I have 3 libraries that I need compiled before I build the main  
project (that needs these 3 libraries).

So Library 1 must compile OK, then Library 2, then Library 3, then my  
main project can compile.

Can anyone provide advice?

best,

-jason
