Since commit v3.9.0-rc1~148^2 (Do not assume GCC libs are linked by all
compilers, 2017-05-05) we no longer filter out all `gcc*` implicit link
libraries. This allows mixing of gcc and non-gcc compilers across
languages. However, this caused a subtle problem with how GCC makes
exception handling symbols available to linked binaries.
GCC (at least on MinGW) provides two different libraries with exception
handling symbols:
* gcc_s: A shared library with -fvisibility=default, used by -shared-libgcc.
* gcc_eh: A static library with -fvisibility=hidden, used by -static-libgcc.
The C compiler (on MinGW) defaults to -static-libgcc and uses gcc_eh.
The C++ compiler defaults to -shared-libgcc and uses gcc_s when linking
shared libraries and executables so that exceptions can propagate across
shared libraries [1]. When linking a mixed-language binary, the C++
compiler should be used along with its choice of gcc_s. In this case
gcc_eh should not be added even though the C compiler implies it because
gcc_s supersedes it.
Since the above-mentioned change, CMake is adding gcc_eh to C++ link
lines that also contain C code on MinGW. This causes both gcc_s and
gcc_eh to be used, which is incorrect. We can fix this simply by
excluding gcc_eh from the C compiler's implicit link libraries.

Refactoring in commit v3.10.0-rc1~115^2 (Clean up iwyu code to not be
one big if statement, 2017-08-28) incorrectly changed the logic to run
only one lint tool at a time. Restore support for running all tools
specified on the command-line.
In commit v3.5.0-rc1~8^2~2 (Help: Clarify policy `CMP0040`
documentation, 2016-01-28) the documentation was clarified to indicate
that the target must be defined in the current directory. Do the same
for the text of the policy warning itself.

The change in commit v3.8.0-rc1~276^2 (Allow NO_SYSTEM_FROM_IMPORTED on
imported INTERFACE libraries, 2016-11-21) was incorrect. The property
is not meant to be set on imported targets at all. It is meant to be
set on their consumers that compile sources. Since INTERFACE libraries
have no sources to compile, the property is not needed on them.
Revert most of that change. Unfortunately we must still tolerate
project code setting NO_SYSTEM_FROM_IMPORTED on INTERFACE libraries
because they were allowed by CMake 3.8 and 3.9.

CPACK_DEBIAN_PACKAGE_VERSION variable could in the past also
contain release and epoch version so regex test should expect
the entire versioning if both CPACK_DEBIAN_PACKAGE_RELEASE
and CPACK_DEBIAN_PACKAGE_EPOCH are not set.
Also since the checks were not performed in the past the regex
test of CPACK_DEBIAN_PACKAGE_VERSION variable content should
only report author warnings instead of errors in case of the
test fail.

The archiver output in the case of universal binaries has changed
slightly. Update our expected output to match. While at it, drop
unnecessary leading and trailing `.*`.
- The .desc files will be in the same folder as the generated .cc and .h files.
- Paths to generate .desc files are stored in a variable passed in
- This is only implemented for C++
- Remove legacy ARGS
- Add test that generates and uses C++ protobuf message
- Add test that checks that the generated .desc file can be instantiated
with DynamicMessageFactory
- Add Help rst for new feature
Add a test for this case to verify the messages. This test will also be
valuable to cover this code path in which we've had several regressions
recently.
The VS_SHADER_OUTPUT_HEADER_FILE property is the name of the generated
header file containing the object code of the shader.
The VS_SHADER_VARIABLE_NAME property is the name of the variable
containing the object code in the above header file.

Prior to commit v3.4.0-rc1~264^2~1 (GetPrerequisites: Add error checks
for execute_process() calls, 2015-07-29), `get_prerequisites` would
simply warn on a missing binary and not update the result list at all.
That commit accidentally made the case an error. This was fixed by
commit v3.8.0-rc1~110^2 (GetPrerequisites: Do not fail on files we
cannot find, 2017-01-10), but the fix also cleared the result list.
Clearing the list is incorrect because it is supposed to be able to
accumulate results over multiple calls.
Remove the list clearing behavior to restore the original behavior on a
missing binary.

Since commit v3.0.0-rc1~448^2 (Ninja: use deps = gcc/msvc feature,
2013-10-18) the value of the `DEP_FILE` binding already includes the
needed quoting to refer to the file. However, that commit forgot to
update one of the `$DEP_FILE` references to not be quoted anymore.
The offending code path currently only affects cmcldeps for RC.
Remove the extra quoting now.

Find GLVND components if available. Add `GLX` and `EGL` options for
COMPONENTS that allow requesting these libraries explicitly. Introduce
new import targets for these windowing-system-specific libraries.
On a GLVND system, populate the legacy `OPENGL_LIBRARIES` variable and
the `OpenGL::GL` target using the `OpenGL` and `GLX` components. On
non-GLVND systems, continue to use the legacy `GL` library and simply do
not provide the GLVND components. Application code can choose to adapt
based on the availability of GLVND components as imported targets.
The change in commit 3b95ab5693 (Performance: Improve efficiency of
source file lookup in cmMakefile, 2017-08-17) broke some legacy behavior
of source file properties in which the order sources are first resolved
with extensions affects how setting properties without extensions works.
It has been reverted for now, but the discovery was made after merging
because the broken case was not covered by our test suite.
Add a test case representing the legacy behavior.

In post-3.9 development we've taught CMake to understand C++ language
standards for MSVC. The RunCMake.try_compile test needs to know whether
to expect support or not. Previously we depended on the host CMake
version to know this, but CMake 3.9 and below do not. Add special logic
to the test to account for this.
Adds support for epoch version to CPackRPM and
CPackDeb packagers.
Also adds better version checking to CPackDeb
that complies with Debian rules.
