-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.
