If the toolchain file or cache does not set this, enable it
automatically based on the Android API version.  Versions 16
and above expect position independent code.

Use the main `CMAKE_POSITION_INDEPENDENT_CODE` setting in favor of
hard-coding `-fpic` or `-fPIC` in the compiler flags for each ABI.
This allows CMake to use `-fpie` or `-fPIE` as needed when sources
are meant for executables, and `-fpic` or `-fPIC` for other sources.

See `${ndk}/build/core/default-build-commands.mk` for link flags the NDK
uses for executables.  Add them to our default executable link flags.
Suppress `nocopyreloc` on `arm64-v8a` because it does not work with
some STL types.

Closes: #16380

Add missing "unwind" and "atomic" libraries needed for this combination.
See `${ndk}/sources/cxx-stl/llvm-libc++/libs/armeabi/libc++.a` for the
libraries the NDK uses.

Issue: #16380

Test with architecture `armv7-a` instead of `armv7-a-hard` because the
latter is supporte supported only with NDK revisions r9c to r11c.

The guard added by commit v3.7.0-rc1~229^2~17 (Android: Suppress new
functionality with Nsight Tegra in VS IDE builds, 2016-06-02) to
`Modules/Platform/Android-Determine.cmake` does not work in that
location because `CMAKE_VS_PLATFORM_NAME` is not set until after the
module is loaded.  Change this particular guard to test for the Visual
Studio generator instead.  If in the future we add support for using
Visual Studio for Android without Nsight Tegra then something more will
be needed, but this is good enough for now.

Closes: #16371

This allows it to be used in expansions without being conditional based
on its value.

Property values may be empty; instead make sure they exist and allow for
empty values.

Do not treat a pointer itself as a `uv_stream_t`, but instead the
pointed-to `uv_pipe_t`.  It is unclear how this ever worked before in
local testing.

While at it, remove duplicate setup code and improve an error message.

The change in commit v3.7.0-rc1~217^2 (FindwxWidgets: Add VS-versioned
library directory prefixes, 2016-08-24) works only for official
wxWidgets builds that add the VS-versioned directory prefixes.  Local
wxWidgets builds still have an unversioned prefix.  Search them.

The change in commit v3.4.0-rc2~6^2 (Xcode: Adjust deployment target SDK
version to host version, 2015-10-11) does not make sense when
cross-compiling.  Make it conditional to fix this regression in some
cross-compiling cases.

Closes: #16355

Explicitly state that this marks the `.xml` to tell the dashboard
server to append it to previously submitted results and that it
does not cause results to be appended to the `.xml` file.

The condition added by commit v2.8.12~179^2 (OS X: Fix regression
handling frameworks for Ninja, 2013-07-16) for excluding use of
versioning symlinks on macOS Frameworks must match that used for
POST_BUILD selection.  Otherwise we place the POST_BUILD commands after
a symlink step that is never added.

Explicitly setting variable CMAKE_LINK_WHAT_YOU_USE or property
LINK_WHAT_YOU_USE to OFF should not cause LWYU to run.  Fix the
property lookup to use GetPropertyAsBool.

In commit v3.7.0-rc1~275^2 (Ninja: Use full path for all source files,
2016-08-05), the source path was changed to use an absolute path.
Inside of `cmcldeps` for `.rc` file compilation, it uses a separate
argument for the path to the source file.  This ended up causing
`cmcldeps` to transform the following call:

    cmcldeps.exe RC source.rc ... C:/full/path/to/source.rc

into:

    ... C:/full/path/to//Tc source.rc

which is invalid.  Update the source filename to use the full path to
the source file so that the path is replaced properly.

Refactoring in commit v3.7.0-rc1~291^2~1 (Refactor extra generator
registration to use factories, 2016-07-20) accidentally switched
the order of the "extra - base" generator names to "base - extra".
Switch it back.  While this could affect all callers of the
`GetRegisteredGenerators` method, only cmake-gui actually used this
particular field.

Fix passing a list to the CMAKE_CACHE_ARGS and CMAKE_CACHE_DEFAULT_ARGS
options of ExternalProject_Add.

Following commit v3.7.0-rc1~273^2~1 (prefer list(APPEND) over
string(APPEND) where appropriate, 2016-08-08), the semicolon list
separator after the first list element was missing in the generated
cache.

In commit v3.7.0-rc1~156^2~1 (VS: Update v140 flag tables from VS 15
MSBuild files, 2016-09-02) we extended the v140 flag table with values
from the v141 toolset that comes with VS 15.  However, the v140 toolset
that comes with VS 14 does not have all of these entries and so the
flags just need to be passed without special mapping.  In order to
support both toolsets, split our CL flag table into separate copies for
each version and switch off the toolset name.

      dfe9b386 SystemTools: Re-implement Strucmp

When a `PREBUILT_STATIC_LIBRARY` uses C++ in its sources then the `.a`
file will have a link-time dependency on the C++ runtime libraries.
Android NDK r14 will add a way to give this information to the NDK build
system by adding a `LOCAL_HAS_CPP` setting to the `Android.mk` file.
Add this for exported static libraries that use C++.
