Uupdate value of variable

[icvallejo]

Hello all, I'm rookie with gnu make and I have a question; I'm doing a
Makefile like this:

#!/bin/bash
# Makefile

IMPORT_PATH := github.com/...
CHECK := 0

.PHONY: install
install:
        $Q printf "\\nLet's install..."
#             $Q export CHECK=0
        $Q if grep -q \!string "$(DIR)" ; then CHECK = $($CHECK + 1) ; fi
        $Q printf "done!"



I want that if the condition is good, update the value of CHECK from 0 to 1,
but I don't know how can I do this :S

Can you help me please ? Thank you!
