FindWish
--------
Finds ``wish``, a simple windowing shell command-line executable.
This module is commonly used in conjunction with finding a TCL installation (see
the :module:`FindTCL` module). It helps determine where the TCL include paths
and libraries are, as well as identifying the name of the TCL library.
If the :variable:`UNIX` variable is defined, the module will prioritize looking
for the Cygwin version of ``wish`` executable.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may be set:
``TK_WISH``
The path to the ``wish`` executable.
Examples
^^^^^^^^
Finding ``wish``:
.. code-block:: cmake
find_package(Wish)
message(STATUS "Found wish at: ${TK_WISH}")
