Copying Python script in rootfs with buildroot

I'm trying to include my Python scripts in my Linux image (for Raspberry Pi). I have 11 scripts and I would like to have them in a file who looks like: /app/scripts/all_my_python_scripts.py Thanks to that, I will be able to call script after boot time to start daemon automatically.

Currently, I am having these .mk and Config.in files in /path-to-buildroot/buildroot/package/python-scripts :

Config.in

config BR2_PACKAGE_PYTHON_SCRIPTS
    bool "python-scripts"
    default "y"
    help
      Import all Python (3.7.2) scripts

python-scripts.mk

PYTHON_PYTHON_SCRIPTS_VERSION = 1.0
PYTHON_PYTHON_SCRIPTS_SOURCE = ../../scripts/
PYTHON_PYTHON_SCRIPTS_LICENSE = BSD-3-Clause
PYTHON_PYTHON_SCRIPTS_TYPE = distutils

define PYTHON_PYTHON_SCRIPTS_COPY
    @$(call MESSAGE,"Syncing python scripts to $(TARGET_DIR)")
    cp ../../scripts/* $(TARGET_DIR)/scripts/
endef
$(eval $(generic-package))

I tried to modify the source path and the "generic-package" but still the same issue. I also correctly update buildroot/package/Confin.in and I double-checked with make menuconfig. I am currently trying to tar my python scripts (before compilation) store them in buildroot/dl and exact them via the makefile, but it doesn't sound logic at all ... I suppose an easier way exist.

Sometime buildroot try to download some file ... sometime it compiling but nothing happen. However, I notice I can't see my 'call MESSAGE', I am missing something ...
