For a recipe folder like this:

.
├── files
│   ├── a.txt
│   ├── b.c
│   └── Makefile
└── myrecipe.bb

You can use the following recipe to install it on a specific folder into your rootfs:

SRC_URI = " file://*"
do_install() {
    install -d ${WORKDIR}/my/dir/on/rootfs
    install -m 0755 ${S}/* ${WORKDIR}/my/dir/on/rootfs/*
}
FILES_${PN} = "/my/dir/on/rootfs/* "
