# ******************************* Documentation ********************************
# 1.Rules
# 	- all: Default rule. Compiles the program.
# 	- clean: Removes all object files and debug files.
# 	- fclean: Removes all object files, debug files, and the executable.
# 	- re: Removes all object files, debug files, executable, and recompiles the
# 		program.
# 	- test: Compiles and runs the test suite for the specified unit.
# 		- Note: this rule expects a make argument called UNIT.
# 	- testall: Compiles and runs all test suites.

# 2.Make arguments
# 	2.1.Build mode arguments
# 		- LEAKS: Compiles the program in leak check mode (-g & -D LEAKS)
# 			- Note: This mode uses 'leaks' command from MacOS, hence it is only
# 				available on MacOS.
# 		- DEBUG: Compiles the program in debug mode (-g only).
# 		- RELEASE: Compiles the program in release mode (-Ofast & -flto).
# 		- Note: The default mode is development mode (-g & -fsanitize=address).

# 	2.2.Other arguments
# 		- RUN: If set, the program will be run after compilation.
# 			- Note: This argument is meant to be used with the all rule only!

# 3.Custom configuration

# 	3.1.Directories section
# 		- SRC_DIR: The directory containing the source files.
# 		- OBJ_DIR: The directory where the object files will be stored.
# 		- INC_DIR: The directory containing the header files.
# 		- TEST_DIR: The directory containing the test files.

# 	3.2.Files section
# 		- NAME: The name of the executable.
# 		- SRCS: This variable uses the find command to find all source files in
# 			the SRC_DIR directory. This should be changed to a static list of
# 			sources files before pushing to 42 intra.

# 	3.3.Compiler options section
# 		- CXX: The compiler to use.
# 		- CXXFLAGS: The compiler flags to use.
# 			- Note: -MMD is used to generate header dependencies.

# 	3.4.Make flags section
# 		- MAKEFLAGS: The make flags to use.
# 			- Note: --silent is used to silence the make output.

#	3.5.Test configuration section
#		- TEST_NAMES: A list of all test suite names.
#			- Note: Please make sure to add all test suite names here.
#			- Note: This is used by the testall rule.
#		- $(UNIT)_DEP: A list of external dependencies for the specified unit.
#			- Note: Please make sure to add all external dependencies here.
