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names and years are hard to maintain and often out-of-date or plain wrong.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.
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

Refactor the local generator creation API to accept a
cmState::Snapshot. Adjust MakeLocalGenerator to use the 'current'
snapshot in cases where there is no parent. Create the snapshot
for subdirectories in cmMakefile::AddSubdirectory.
This means that snapshots are now created at the point of extending the tree,
as appropriate, and independently of the cmLocalGenerator and cmMakefile they
represent the state for.
The Borland generator re-implements every method the NMake generator
does, so there is no reason to inherit this way. Instead inherit
directly from cmGlobalUnixMakefileGenerator3 like all the other
makefile generators do.
Add .DELETE_ON_ERROR to the "build.make" files that contain the actual
build rules that generate files. This tells GNU make to delete the
output of a rule if the recipe modifies the output but returns failure.
This is particularly useful for custom commands that use shell
redirection to produce a file.
Do not add .DELETE_ON_ERROR for Borland or Watcom make tools because
they may not tolerate it and would not honor it anyway. Other make
tools that do not understand .DELETE_ON_ERROR will not be hurt.

Add the .NOTPARALLEL target to each local Makefile command-line
interface entry point file so that even with -j we launch only
one "make -f Makefile2" at a time. The actual build rules
in Makefile2 and lower will still run in parallel.
Do not add .NOTPARALLEL for Borland or Watcom make tools because
they do not tolerate it. Other make tools that do not understand
.NOTPARALLEL will not be hurt.

This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
something like this:
ENABLE_LANGUAGE(ASM-ATT)
IF(CMAKE_ASM-ATT_COMPILER_WORKS)
... do assembler stufff
ELSE(CMAKE_ASM-ATT_COMPILER_WORKS)
... fallback to generic C/C++
ENDIF(CMAKE_ASM-ATT_COMPILER_WORKS)
