The correct flag is -C, not -c. In make --help you can see:

 -C DIRECTORY, --directory=DIRECTORY
                             Change to DIRECTORY before doing anything.

which is what you want (ie: change to the kernel's build directory).
Also make sure you don't actually have any spaces in the path name,
which it looks like you do. Try this:

make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
