If I add my simple1 and simple2 recipes to IMAGE_INSTALL I get the following error in the do_rootfs task:
* opkg_install_cmd: Cannot install package simple1. 

I assumed that this is because there really is nothing to install in the image as this is a static library with nothing that should go in the image.

Again if I try adding this to my image recipe I get a similar error
* opkg_install_cmd: Cannot install package simple1-staticdev.

For reference here is my simple1 recipe, maybe I'm missing something in there. 

DESCRIPTION = "Simple library 1."
LICENSE = "CLOSED"
LIC_FILES_CHKSUM = ""

SRC_URI = "git://git@gitlab.work.net/libs/simple1.git;protocol=ssh"
SRCREV = "${AUTOREV}"

S = "${WORKDIR}/git" 

inherit pkgconfig cmake
