# FindGTK2

Find the GTK2 widget libraries and several of its other optional components like `gtkmm`, `glade`, and `glademm`.

Specify one or more of the following components as you call this find module. See example below.

- `gtk`

- `gtkmm`

- `glade`

- `glademm`

## Imported Targets

This module defines the following `IMPORTED` targets (subject to component selection):

`GTK2::atk`, `GTK2::atkmm`, `GTK2::cairo`, `GTK2::cairomm`, `GTK2::gdk_pixbuf`, `GTK2::gdk`, `GTK2::gdkmm`, `GTK2::gio`, `GTK2::giomm`, `GTK2::glade`, `GTK2::glademm`, `GTK2::glib`, `GTK2::glibmm`, `GTK2::gmodule`, `GTK2::gobject`, `GTK2::gthread`, `GTK2::gtk`, `GTK2::gtkmm`, `GTK2::harfbuzz`, `GTK2::pango`, `GTK2::pangocairo`, `GTK2::pangoft2`, `GTK2::pangomm`, `GTK2::pangoxft`, `GTK2::sigc`.

New in version 3.16.7: Added the `GTK2::harfbuzz` target.

## Result Variables

The following variables will be defined for your use

`GTK2_FOUND`

  Were all of your specified components found?

`GTK2_INCLUDE_DIRS`

  All include directories

`GTK2_LIBRARIES`

  All libraries

`GTK2_TARGETS`

  New in version 3.5: All imported targets

`GTK2_DEFINITIONS`

  Additional compiler flags

`GTK2_VERSION`

  The version of GTK2 found (x.y.z)

`GTK2_MAJOR_VERSION`

  The major version of GTK2

`GTK2_MINOR_VERSION`

  The minor version of GTK2

`GTK2_PATCH_VERSION`

  The patch version of GTK2

New in version 3.5: When `GTK2_USE_IMPORTED_TARGETS` is set to `TRUE`, `GTK2_LIBRARIES` will list imported targets instead of library paths.

## Input Variables

Optional variables you can define prior to calling this module:

`GTK2_DEBUG`

  Enables verbose debugging of the module

`GTK2_ADDITIONAL_SUFFIXES`

  Allows defining additional directories to search for include files

## Example Usage

Call `find_package()` once. Here are some examples to pick from:

Require GTK 2.6 or later:

    find_package(GTK2 2.6 REQUIRED gtk)

Require GTK 2.10 or later and Glade:

    find_package(GTK2 2.10 REQUIRED gtk glade)

Search for GTK/GTKMM 2.8 or later:

    find_package(GTK2 2.8 COMPONENTS gtk gtkmm)

Use the results:

    if(GTK2_FOUND)
      include_directories(${GTK2_INCLUDE_DIRS})
      add_executable(mygui mygui.cc)
      target_link_libraries(mygui ${GTK2_LIBRARIES})
    endif()
