simple loop over files in some directory makefile

Question

I can easily print all the files inside some directory from bash:

$ cat go.sh
BASEDIR=~/Downloads
MYDIR=${BASEDIR}/ddd
for f in $(ls ${MYDIR}); do echo $f; done

$ ./go.sh
m.txt
d.txt

When I try to do a similar thing from makefile it doesn't work well:

$ cat makefile
BASEDIR = ${HOME}/Downloads
MYDIR = ${BASEDIR}/ddd
all:
    for f in $(ls ${MYDIR}); do echo ${f}; done

$ make
for f in ; do echo ; done

And here is another trial that doesn't work:

$ cat makefile
BASEDIR = ${HOME}/Downloads
MYDIR = ${BASEDIR}/ddd
all:
    for f in $(shell ls ${MYDIR}); do echo ${f}; done

$ make
for f in d.txt m.txt; do echo ; done

Here is the edited answer based on @Oo.oO:

$ cat makefile
BASEDIR = ${HOME}/Downloads
MYDIR = ${BASEDIR}/ddd
all:
    @for f in $(shell ls ${MYDIR}); do echo $${f}; done

$ make
d.txt
m.txt
