FindGTK
-------
.. note::
This module works only on Unix-like systems and was intended for early GTK
branch of 1.x, which is no longer maintained. Use the latest supported GTK
version and :module:`FindPkgConfig` module to find GTK in CMake instead of
this module. For example:
.. code-block:: cmake
find_package(PkgConfig REQUIRED)
pkg_check_modules(GTK REQUIRED IMPORTED_TARGET gtk4>=4.14)
target_link_libraries(example PRIVATE PkgConfig::GTK)
Finds GTK, glib and GTKGLArea:
.. code-block:: cmake
find_package(GTK [...])
GTK is a multi-platform toolkit for creating graphical user interfaces.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``GTK_FOUND``
Boolean indicating whether GTK was found.
``GTK_GL_FOUND``
Boolean indicating whether GTK's GL features were found.
``GTK_INCLUDE_DIR``
Include directories containing headers needed to use GTK.
``GTK_LIBRARIES``
Libraries needed to link against for using GTK.
Examples
^^^^^^^^
Finding GTK 1.x and creating an interface :ref:`imported target
<Imported Targets>` that encapsulates its usage requirements for linking to a
project target:
.. code-block:: cmake
find_package(GTK)
if(GTK_FOUND)
add_library(GTK::GTK INTERFACE IMPORTED)
set_target_properties(
GTK::GTK
PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES "${GTK_INCLUDE_DIR}"
INTERFACE_LINK_LIBRARIES "${GTK_LIBRARIES}"
)
endif()
target_link_libraries(example PRIVATE GTK::GTK)
See Also
^^^^^^^^
* The :module:`FindGTK2` module to find GTK version 2.
