Brad King 86578eccf2 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names and years are hard to maintain and often out-of-date or plain wrong.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.

Brad King a85e17e660 Intel: When simulating MSVC, re-use Windows-MSVC (#14476)
Teach CMake(C|CXX|Fortran)CompilerId* to report the MSVC version
simulated by the Intel compiler, if any.  Refactor the Windows-Intel
platform information helper module to load Windows-MSVC instead of
duplicating the information.  Teach Windows-MSVC to understand when
it is loaded as the simulated Fortran compiler (its preprocessor is
simulated).

Brad King 42ba1b08f3 VS: Separate compiler and linker PDB files (#11899, #14062)
The MS tools create two types of PDB files as explained here:

 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.71%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.80%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.90%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.100%29.aspx

One is created by the compiler (/Fd) and the other by the linker (/pdb).
The two options should not specify the same file.  Split them up.

In the VS IDE generators, simply drop ProgramDataBaseFileName to
take the VS default "/Fd$(IntDir)vc$(PlatformToolsetVersion).pdb".

In the Makefile generators, set "/Fd" on the compile line to be
the directory containing object files (with a trailing slash the
compiler will add the "vc$(PlatformToolsetVersion).pdb" filename
automatically).  Drop the /Fd option from the exe link command
line and add "/pdb" instead (already done for dll linking).
Update these rules for both MSVC and Intel tools.

Drop support for PDB_OUTPUT_DIRECTORY and PDB_NAME in STATIC
libraries because the generated .pdb files are only from /Fd
and not real linker-generated .pdb files.  Update documentation to
clarify that the PDB_* properties are only for linker .pdb files.

This regresses the PDBDirectoryAndName test for STATIC libraries.
Since it is not clear at this time what should be done for STATIC
library .pdb files, comment out the relevant portion of the test
and leave a TODO comment.

David Cole 51af1da3d2 CMake: Remove "/STACK:10000000" from default linker flags (#12437)
Modern apps that use multiple threads do NOT want 10 Megabytes of RAM
per thread being used for each thread's stack... Just leave off the
/STACK: argument, and let the compiler use a reasonable default value
for the stack size.

If existing single-threaded apps require the /STACK: argument because
they do need a very large stack size, they can add the flag in their
own CMakeLists files.

Peter Kümmel e31df03939 Ninja: move <OBJECTS> in front of the first linker option
In the response file also linker options could be passed,
and because <OBJECTS> is replaced by a response file, it
is necessary that no compiler option follows <OBJECTS>.

Bill Hoffman dbd99d6fbb Revert "Ninja: don't expand any rsp files"
This reverts commit 5598d9b2a0.

Since commit f1670ab1 (Ninja: don't confuse ninja's rsp files with
nmake's, 2012-09-26) Ninja generator response files are placed in
CMakeFiles/ so the previously existing check already avoids expanding
them.

Brad King 7195aca54f Make platform information files specific to the CMake version
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use.  The
method of detection and the exact results store varies across CMake
versions as things improve.  This leads to problems when loading files
configured by a different version of CMake.  Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files.  This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).

Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version.  Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake.  Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.

Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose.  The new variable points
at the version-specific directory while the old variable did not.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

Run the following shell code:

git ls-files -z -- \
 bootstrap doxygen.config '*.readme' \
 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
 '*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |
egrep -z -v '^(Modules/CPack\..*\.in)' |
xargs -0 sed -i 's/ \+$//'
