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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

# FindQt3
# -------
#
# Locate Qt include paths and libraries
#
# This module defines:
#
# ::
#
# QT_INCLUDE_DIR - where to find qt.h, etc.
# QT_LIBRARIES - the libraries to link against to use Qt.
# QT_DEFINITIONS - definitions to use when
# compiling code that uses Qt.
# QT_FOUND - If false, don't try to use Qt.
# QT_VERSION_STRING - the version of Qt found
#
#
#
# If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
# TRUE
#
# Also defined, but not for general use are:
#
# ::
#
# QT_MOC_EXECUTABLE, where to find the moc tool.
# QT_UIC_EXECUTABLE, where to find the uic tool.
# QT_QT_LIBRARY, where to find the Qt library.
# QT_QTMAIN_LIBRARY, where to find the qtmain
# library. This is only required by Qt3 on Windows.
# These are around for backwards compatibility
# they will be set
# QT_WRAP_CPP, set true if QT_MOC_EXECUTABLE is found
# QT_WRAP_UI set true if QT_UIC_EXECUTABLE is found
# If Qt4 has already been found, fail.
