[yocto] do_install_append_class-target(): Files are not being installed on the system

[yocto yocto]

Good day,

I am writing a recipe using "inherit autotools". I am using
"do_install_append_class-target()" to install all files on the system. The
folder

build/tmp/work/core2-32-poky-linux/my-recipe/x.y.z-r0/image

contains all files respectively the desired folder structure. However,
after flashing my image all folders and files are not there. What might be
the problem?
