# FindGTK

Finds GTK, glib and GTKGLArea.

GTK is a multi-platform toolkit for creating graphical user interfaces.

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This module works only on Unix-like systems and was intended for early GTK branch of 1.x, which is no longer maintained.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 `FindPkgConfig` module to find GTK in CMake instead of this module. For example:

    find_package(PkgConfig REQUIRED)
    pkg_check_modules(GTK REQUIRED IMPORTED_TARGET gtk4>=4.14)
    target_link_libraries(example PRIVATE PkgConfig::GTK)

## Result Variables

This module defines the following variables:

`GTK_FOUND`

  Boolean indicating whether GTK is found.

`GTK_GL_FOUND`

  Boolean indicating whether GTK's GL features are 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 imported target that encapsulates its usage requirements for linking to a project target:

    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)
