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.
