# 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`

## 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`
  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

## 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()
