make is a task runner for targets described in Makefile. Mostly used to control the compilation of an executable from source code.

# To call the first target specified in the Makefile (usually named "all"):
make

# To call a specific target:
make target

# To use a specific Makefile:
make --file file

# To execute make from another directory:
make --directory directory

# To force making of a target, even if source files are unchanged:
make --always-make target
