Make files aren't like shell scripts.  Each line of execution inherits the
the same environment.  For example:

all:
        ls
        cd dir1
        ls

Both ls commands will output the same value(s).  That being said, the key is
"each line of execution".  So, keep the commands on the same line and it
will work:

all:
        ls ; cd dir1 ; ls

Also, if you call make from inside a Makefile (recursively), use the ${MAKE}
macro.  So, your Makefile would look like this:

all:
        cd folder1 ; ${MAKE}
        cd folder2 ; ${MAKE}
        cd folder3 ; ${MAKE}
