Building yocto and legato using leaf

I have done the following steps:

wget https://downloads.sierrawireless.com/tools/leaf/leaf_latest.deb -O /tmp/leaf_latest.deb && sudo apt install /tmp/leaf_latest.deb
mkdir ~/Leaf; cd ~/Leaf
leaf init
leaf remote add external-stable https://downloads.sierrawireless.com/leaf/legato/stable.json
leaf search wp76
leaf setup -p swi-wp76_5.0.0
leaf profile -v
leaf getsrc swi-linux
leaf getsrc swi-legato

all sources ware fetched OK

then when building I get this errorL
I get this error
$ make
make: *** No targets specified and no makefile found. Stop.

please advice

how about download yocto source by using github?

Example on downloading WP76 yocto source from Github.docx (90.5 KB)

I managed now to fully build from source by downloading the Yocto source from GITHUB
