FindGnuTLS

Finds the GNU Transport Layer Security library (GnuTLS):

find_package(GnuTLS [<version>] [...])

The GnuTLS package includes the main libraries (libgnutls and libdane), as well as the optional gnutls-openssl compatibility extra library. They are all distributed as part of the same release. This module checks for the presence of the main libgnutls library and provides usage requirements for integrating GnuTLS into CMake projects.

Imported Targets

This module provides the following Imported Targets:

GnuTLS::GnuTLS

Added in version 3.16.

Target encapsulating the GnuTLS usage requirements, available if GnuTLS is found.

Result Variables

This module defines the following variables:

GnuTLS_FOUND

Added in version 3.3.

Boolean indicating whether (the requested version of) GnuTLS was found.

GnuTLS_VERSION

Added in version 4.2.

The version of GnuTLS found.

GNUTLS_INCLUDE_DIRS

Include directories needed to use GnuTLS.

GNUTLS_LIBRARIES

Libraries needed to link against to use GnuTLS.

GNUTLS_DEFINITIONS

GNUTLS_LIBRARY

The path to the GnuTLS library.

Deprecated Variables

The following variables are provided for backward compatibility:

GNUTLS_FOUND

Deprecated since version 4.2: Use GnuTLS_FOUND, which has the same value.

Boolean indicating whether (the requested version of) GnuTLS was found.

GNUTLS_VERSION_STRING
