Unable to build as dependencies are missing in recipe-sysroot - yocto - cmake

Question

I'm trying to build mxnet 1.6.0 with Yocto (Rocko) for my 64-bit Armv8-A.
First of all, I have downloaded mxnet from https://downloads.apache.org/incubator/mxnet/1.6.0/ .
I have kept the downloaded tar in files folder in one of the layers. and i have included that tar file in my mxnet.bb file as shown below.
mxnet.bb
SUMMARY = "MXNET Package"
SECTION = "libs"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
PN = 'mxnet'
PV = '1.6.0'
DEPENDS = "openblas opencv gtest gperftools"
SRC_URI := " \
file://apache-mxnet-src-1.6.0-incubating.tar.gz"
SRC_URI[md5sum] = "76802d6b14cd45c27f063b2bba3c9a14"
S := "${WORKDIR}/apache-${PN}-src-${PV}-incubating"
inherit cmake pkgconfig
OECMAKE_GENERATOR = "Unix Makefiles"
EXTRA_OECMAKE += " -DUSE_SSE=OFF \
-DUSE_CUDA=OFF \
-DUSE_OPENCV=ON \
-DUSE_OPENMP=ON \
-DUSE_MKL_IF_AVAILABLE=OFF \
-DUSE_SIGNAL_HANDLER=ON \
-DUSE_LAPACK=OFF"
Then I built it using bitbake mnxet command.
I got the below error.

I checked in build/tmp/work/aarch64-poky-linux/openblas/0.3.5-r0/image/opt/openblas/lib and found .so and .a files.
I noticed that in
build/tmp/work/aarch64-poky-linux/mxnet/1.6.0-r0/recipe-sysroot/lib64,
there is no libopenblas.so or openblas folder.
I also checked build/tmp/sysroots-components/aarch64/openblas
and found that there's only sysroot-providers in it and no opt/openblas/lib or any opt or lib folder (I can't find files present in my image folder of openblas as mentioned above).
So, the question is, How do i add openblas to my recipe-sysroot in mxnet? so that it should not throw couldn't find openblas error?
p.s. I could build openblas only if my .so files were present in /opt/openblas/lib path. Else, if i try to put .so files in just /lib folder, it would throw me a Files/directories were installed but not shipped in any package error.

Answer 1

you can try to add
FILES_${PN} = "${libdir}/libmxnet.so"
to the recipe.
