+FindCURL
+--------
+
+Find the native CURL headers and libraries.
+
+This module accept optional COMPONENTS to check supported features and
+protocols::
+
+ PROTOCOLS: ICT FILE FTP FTPS GOPHER HTTP HTTPS IMAP IMAPS LDAP LDAPS POP3
+ POP3S RTMP RTSP SCP SFTP SMB SMBS SMTP SMTPS TELNET TFTP
+ FEATURES: SSL IPv6 UnixSockets libz AsynchDNS IDN GSS-API PSL SPNEGO
+ Kerberos NTLM NTLM_WB TLS-SRP HTTP2 HTTPS-proxy
+
+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.
+
+CURL CMake
+^^^^^^^^^^
+
+If CURL was built using the CMake buildsystem then it provides its own
+``CURLConfig.cmake`` file for use with the :command:`find_package` command's
+config mode. This module looks for this file and, if found,
+returns its results with no further action.
+
+Set ``CURL_NO_CURL_CMAKE`` to ``ON`` to disable this search.
