# FindCURL
# --------
#
# Find the native CURL headers and libraries.
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines :prop_tgt:`IMPORTED` target ``CURL::libcurl``, if
# curl has been found.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module defines the following variables:
#
# ``CURL_FOUND``
# True if curl found.
#
# ``CURL_INCLUDE_DIRS``
# where to find curl/curl.h, etc.
#
# ``CURL_LIBRARIES``
# List of libraries when using curl.
#
# ``CURL_VERSION_STRING``
# The version of curl found.
# Look for the header file.
