makefile running order

[danchoy]

Hi, I'm not sure if I'm a weird case.
Here is my case, normally when I run my makefile on Linux I put the variable DEPS under the CFLAGS line without any issues.
I just installed brew and SFML on my macOS then I modified my makefile to set the paths to my local SFML includes and libraries.
Strangely, after I put the path into the makefile and run it, it prompts me with an error saying the SFML/anyfile.hpp file cannot be found.

Finally, I found that if I relocated the variable DEPS below the compile session, it ran it successfully.

Does anyone else have any ideas?

Thanks

I'd assume if you put it at the bottom then $(DEPS) will simply resolve "nothing", as the variable is only declared further down and thus it runs, but then again I've no idea about the make file syntax.
You don't really need to specify header files when building, the compiler just needs to know where to look for the headers when building all the cpp source files.
