This function will be available as of eric6 18.05 (rev. 36854b779685).

Some suggest of Makefile support functions:

+ User can setting where the make command located at, if there is no path 
set then try to calling global "make" command.

+ A "main makefile" can be added with project properties just like "main 
script".

+ When starting "run project" action, a check box can let user to choose 
should re-make the project or not.

+ Make command can be pass arguments like "-C path/to/makefile", "build-
xxx", etc.

Please give more details about your idea (e.g. how should it be integrated, which 
arguments should be supported or how entering arguments should be performed, 
should the data/arguments be stored within the project file).

Hallo, I have some Makefile processes for my Python script, such like C++ or
Cython libraries.

I hope Eric can let a main Makefile along with project, add a 'build' button to
run it with arguments.
