Hi everyone, first time in the mailing list...

I was wondering if anybody is already working in a recipe for the package dlib pyhon3 module,
so far this is the recipe I've been working on
```bitbake
# python3-dlib_19.21.1.bb
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 \

"
DEPENDS = "cmake-native"

inherit  pypi setuptools3
BBCLASSEXTEND = "native nativesdk"

```


I'm not a bitbake or cmake expert, during do_compile() task i get the following error message

```

Not sure why the linker **gcc/aarch64-poky-linux/8.3.0/ld** is showing the error
```
 error adding symbols: file in wrong format
```
Perhaps i'm messing things up with cmake-native environment but not sure how i can enable cmake to be used by setup.py if it is not with DEPENDS=cmake-native.

Any clue to solve this issue will be highly appreciated, or if you know who is already working on this it will be great to have its contact :)

Also i use dunfell branch for meta-oe

BR,
