GNU make - Include Go to the first , previous , next , last section, table of contents .
The include directive tells make to suspend reading the current makefile and read one or more other makefiles before continuing. Extra spaces are allowed and ignored at the beginning of the line, but a tab is not allowed. If the file names contain any variable or function references, they are expanded. See section How to Use Variables . When make processes an include directive, it suspends reading of the containing makefile and reads from each listed file in turn.
