How to select *.c files with Makefile?

Question

This is a kind of silly question, but this is first time I am using Makefile. I am having trouble with selecting files. When I used this command,

target1:

     $(CC) -o target *.c

it worked well. But this doesn't work,

SRCS = dir1/*.c
target1:

     $(CC) -o target $(SRCS)

and spits this error.

clang: error: no such file or directory: 'dir1/*.c'

Obviously this because my variable SRCS is escaped before passed. How can I make Makefile pass the string as is? Or is there another conventional/designed way to do this? (selecting file by pattern)

You can use the wildcard keyword to select all the files matching a certain pattern like this:

SRCS = $(wildcard dir1/*.c)
target1:

     $(CC) -o target $(SRCS)
