'Python3 cythonize from yocto bitbake recipe problem

Let me say this recipe works just fine on our environment with python 2.7, but on new environment where python3 is not. I have no clue why.

Folder/files structure:

zurka-plugin-extensions-EstTV-py3   ---> Folder
    setup.py
    dialog.py
    main.py
    plugin.pyc
    __init__.pyc
    Esttv.png

BB recipe:

DESCRIPTION = "EstTV"
MAINTAINER = "Est"
PV = "4.0"
PR = "r0"

require conf/license/license-gplv2.inc

DEPENDS = "python3 python3-cython python3-cython-native"
RDEPENDS:${PN} = " python3-requests python3-multiprocessing python3-image python3-json ffmpeg "
RRECOMMENDS:${PN} = " python3-pillow nesto-plugin-systemplugins-kauz "

#inherit pkgconfig lib_package setuptools distutils     #py2 - working solution
inherit pkgconfig lib_package setuptools3               #py3??????

SRC_URI = "file://setup.py \
           file://dialog.py \
           file://main.py \
           file://__init__.pyc \
           file://plugin.pyc \
           file://Esttv.png \
"

S = "${WORKDIR}"

do_compile () {
     python setup.py build_ext --inplace
}

do_install () {
    install -d ${D}${libdir}/zurka/python/Plugins/Extensions/EstTV

    install    ${WORKDIR}/*.pyc  ${D}${libdir}/zurka/python/Plugins/Extensions/EstTV/

    install -m 0755 ${S}/dialog.so ${D}${libdir}/zurka/python/Plugins/Extensions/EstTV/
    install -m 0755 ${S}/main.so ${D}${libdir}/zurka/python/Plugins/Extensions/EstTV/

}

Cythonize script (setup.py):

from distutils.core import setup
from Cython.Build import cythonize

def cythonize_modules():
    return cythonize([
        "dialog.py",
        "main.py",
    ],
        language_level=3,  # python3
    )

setup(ext_modules=cythonize_modules())

Error:

ERROR: zurka-plugin-extensions-EstTV-py3-4.0-r0 do_fetch: Fetcher failure: 
Unable to find file file://__init__.pyc anywhere. 
The paths that were searched were:
    /mnt/h4/7.0/meta-mi/recipes-plugins/zurka-plugin-extensions-EstTV-py3-4.0/mi
    /mnt/h4/7.0/meta-mi/recipes-plugins/zurka-plugin-extensions-EstTV-py3/mi 
    /mnt/h4/7.0/meta-mi/recipes-plugins/files/mi
    /mnt/h4/7.0/meta-mi/recipes-plugins/zurka-plugin-extensions-EstTV-py3/
    etc...

As you can see __init__.pyc is inside folder zurka-plugin-extensions-EstTV-py3.

What about inherit, when i put setuptools (without 3) error is different; Could not inherit file classes/setuptools.bbclass.

When i put setuptools3 error is; missing file (__init__.pyc).

When i put distutils, error is different again (i can't remember which one exactly).

So, what i can do next? Thank you!

EDIT:

after i change do compile line from python setup.py build_ext --inplace to python3 ${S}/setup.py build_ext --inplace now i have another type of error.
