FindTCL
|
|
-------
|
|
|
|
Finds the Tcl (Tool Command Language), dynamic programming language.
|
|
|
|
This module locates a Tcl installation, including its include directories and
|
|
libraries, and determines the appropriate Tcl library name for linking. As part
|
|
of the Tcl ecosystem, it also finds Tk, a GUI toolkit that provides a library of
|
|
basic widgets for building graphical user interfaces.
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module defines the following variables:
|
|
|
|
``TCL_FOUND``
|
|
Boolean indicating whether the Tcl is found.
|
|
``TK_FOUND``
|
|
Boolean indicating whether the Tk is found.
|
|
``TCLTK_FOUND``
|
|
Boolean indicating whether both Tcl and Tk are found.
|
|
|
|
Cache Variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variables may also be set:
|
|
|
|
``TCL_LIBRARY``
|
|
The path to the Tcl library (e.g., ``tcl``, etc.).
|
|
``TCL_INCLUDE_PATH``
|
|
The directory containing ``tcl.h`` and other Tcl-related headers needed to use
|
|
Tcl.
|
|
``TCL_TCLSH``
|
|
The path to the ``tclsh`` command-line executable.
|
|
``TK_LIBRARY``
|
|
The path to the Tk library (e.g., ``tk``, etc.).
|
|
``TK_INCLUDE_PATH``
|
|
The directory containing ``tk.h`` and other Tk-related headers needed to use
|
|
Tk.
|
|
``TK_WISH``
|
|
The path to the ``wish`` windowing shell command-line executable.
|
|
|
|
|
|
Other Libraries
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The Tcl Stub Library can be found using the separate :module:`FindTclStub`
|
|
module.
|
|
|
|
|
|
Examples
|
|
^^^^^^^^
|
|
|
|
Finding Tcl:
|
|
|
|
.. code-block:: cmake
|
|
|
|
find_package(TCL)
|
|
|
|

|
|
^^^^^^^^

|
|
|
* The :module:`FindTclsh` module to find the Tcl shell command-line executable.
|
|
* The :module:`FindTclStub` module to find the Tcl Stubs Library.
|
|
* The :module:`FindWish` module to find the ``wish`` windowing shell
|
|
command-line executable .
