Raw Normal View History

Simplify CMake per-source license notices Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

# TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.
#
# This module finds Tcl stub libraries. It first finds Tcl include
# files and libraries by calling FindTCL.cmake. How to Use the Tcl

# This code sets the following variables:
#
# ::
#
# TCL_STUB_LIBRARY = path to Tcl stub library
# TK_STUB_LIBRARY = path to Tk stub library
# TTK_STUB_LIBRARY = path to ttk stub library
#
#
#
# In an effort to remove some clutter and clear up some issues for
# people who are not necessarily Tcl/Tk gurus/developpers, some
# variables were moved or removed. Changes compared to CMake 2.4 are:
#
# ::
#
# => these libs are not packaged by default with Tcl/Tk distributions.
# Even when Tcl/Tk is built from source, several flavors of debug libs
# are created and there is no real reason to pick a single one
# specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx).
# Let's leave that choice to the user by allowing him to assign
# TCL_STUB_LIBRARY to any Tcl library, debug or not.
