" Could NOT find CURL (missing: CURL_LIBRARY CURL_INCLUDE_DIR)"

What am I doing wrong, I will be glad to any help

Here is Makefile:

include $(TOPDIR)/rules.mk

PKG_NAME:=speedtest
PKG_VERSION:=1
PKG_RELEASE:=1
PKG_BUILD_DIR:=$(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)

include $(INCLUDE_DIR)/package.mk

define Package/speedtest

try to use cmake don't erase them in define Build/Prepare, look for other packages as example and don't add anything to define Build/Configure and define Build/Compile
you can also point the make dir if is in speedtest subfolder
