How do I write the 'cd' command in a makefile?

Question

For example, I have something like this in my makefile:

all:
     cd some_directory

But when I typed make I saw only \'cd some

Starting from GNU make 3.82 (July 2010), you can use the .ONESHELL special target to run all recipe lines in a single instantiation of the shell (bold emphasis mine):

• New special target: .ONESHELL instructs make to invoke a single instance of the shell and provide it with the entire recipe, regardless of how many lines it contains.

.ONESHELL: # Only applies to all target
all:
    cd ~/some_dir
    pwd # Prints ~/some_dir if cd succeeded

another_rule:
    cd ~/some_dir
    pwd # Oops, prints ~
