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names and years are hard to maintain and often out-of-date or plain wrong.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.
When building a project relying on External projects, the launchers were
not used in subprojects built without testing enabled. This was preventing
errors and warnings associated with these subprojects from being
reported on the dashboard.
This commit allows enabling the launchers independently of the value of
"BUILD_TESTING" using one of these two approaches:
1) By setting both CTEST_USE_LAUNCHERS and the env variable
"CTEST_USE_LAUNCHERS_DEFAULT" to 1 in the ctest dashboard driver scripts.
2) By enabling the variable CTEST_USE_LAUNCHERS in the ctest dashboard
driver script and also by ensuring every external project passes the option
-DCMAKE_PROJECT_<projectname>_INCLUDE:FILEPATH=${CMAKE_ROOT}/Modules/CTestUseLaunchers.cmake
