I'm new to Makefile, and I tried to make a simplest Makefile. But I don't understand why even though I'm clearly in the correct path to the Makefile, the make command still says "make: \*\*\* No targets specified and no makefile found. Stop."?~

Here is my Makefile content :
-----------------------------

```
 CC=gcc
 CFLAGS=-I.

 exercise1: exercise1.c
     $(CC) -o exercise1 exercise1.c

```

files in ..TH\Week1 : exercise1.c, Makefile
