Hi @Khem, based on this discussion i tried the following recipe and it worked just fine

SUMMARY = "A toolkit for making real world machine learning and data analysis applications"
HOMEPAGE = "https://pypi.python.org/pypi/dlib"
PYPI_PACKAGE = "dlib"
LICENSE = "Boost-Software"
SRC_URI[md5sum] = "1e7e357d7d54e86267ef60f606cb40e1"
LIC_FILES_CHKSUM = "file://dlib/LICENSE.txt;md5=2c7a3fa82e66676005cd4ee2608fd7d2 \
                    file://dlib/external/libpng/LICENSE;md5=243135ddedf702158f9170807cbcfb66 \
                    file://dlib/external/pybind11/LICENSE;md5=beb87117af69fd10fbf9fb14c22a2e62 \
                    file://python_examples/LICENSE_FOR_EXAMPLE_PROGRAMS.txt;md5=064f53ab40ea2b6a4bba1324149e4fde \
"
DEPENDS = "sqlite3 "

inherit pypi cmake setuptools3
INSANE_SKIP_${PN} = "already-stripped"                          

DISTUTILS_BUILD_ARGS_append = " \
      --set CMAKE_TOOLCHAIN_FILE=${WORKDIR}/toolchain.cmake \
"

I'm not sure if there is a better way to do this and make a PATCH from it
