"Check requirements" command for your Makefile

Makefile

# Use it like this:
#
#     $ printf $(_TITLE) "Something in green" "The message"
#
# This will output something like this:
#
# [Something in green] The message
#
# (of course, with proper colors)
_TITLE := "\033[32m[%s]\033[0m %s\n" # Green text
_ERROR := "\033[31m[%s]\033[0m %s\n" # Red text

# This function has to be used this way:
#
#     @$(call check_binary_command,command name,command line and options to execute)
#
# Example :
#
#     @$(call check_binary_command,PHP,php --version)
#
# Note the absence of spaces between the commas ",".
# If you added spaces, they would be added to the commands or output.
#
# This command will display "[OK] {command name} is installed" 
# if the {command line and options to execute}'s exit code is 0.
# Else, it will display "[KO] {command name} is not installed",
# and the entire Make command will fail,
# thanks to the temporary file defined later in this config.
#
# Side-note:
# $(1) is the first argument, $(2) the second, etc.
# The "@" sign is here to avoid Make to display the full command-line.
#

# This temporary file will be present if *any* check command fails.
# If it is present, it allows the "check-requirements" target to fail too,
# which will prevent Make from executing any further command.
