Makefile feed to download file without checkout repo

Hello,
I want to write a makefile feeds in order to download zip file in a gitlab repo without checkout the repo. here is my makefile:

PKG_NAME:=tarBall
PKG_RELEASE:=1
PKG_SOURCE_VERSION:=$(PKG_VERSION)
PKG_MD5SUM:=skip
PKG_SOURCE_SUBDIR:=${PKG_NAME}
ZIP_FILE:=myfile.zip

define Download/$(PKG_NAME)
	$(info Downloading tarball)
	FILE:=$(ZIP_FILE)
	URL:=https://gitlab-xxx/fies/-/blob/master/
	MD5SUM:=skip
endef
define Package/$(PKG_NAME)/install
	$(info Nothing to install)
endef

define Build/Compile
	$(info Nothing to compile)
	$(eval $(call Download,$(PKG_NAME)))
endef

$(eval $(call BuildPackage,$(PKG_NAME)))

When i launch "make package/sdximages/compile V=s" or "make package/sdximages/download V=s"
It doesn't download the file. Anyone has an idea about this issue please?
