If not specified, a default for this variable will be chosen
as specified :ref:`above <Cross Compiling for Android>`.
:variable:`CMAKE_ANDROID_NDK_DEPRECATED_HEADERS`
Set to a true value to use the deprecated per-api-level headers
instead of the unified headers. If not specified, the default will
be false unless using a NDK that does not provide unified headers.
:variable:`CMAKE_ANDROID_NDK_TOOLCHAIN_VERSION`
Set to the version of the NDK toolchain to be selected as the compiler.
If not specified, the default will be the latest available GCC toolchain.

Variables
---------
* A :variable:`CMAKE_ANDROID_NDK_DEPRECATED_HEADERS` variable was added
for use when :ref:`Cross Compiling for Android with the NDK` to request
use of the deprecated headers even when unified headers are available.
The default is now to use unified headers if available.
* A :variable:`CMAKE_AUTOMOC_DEPEND_FILTERS` variable was introduced to
allow :variable:`CMAKE_AUTOMOC` to extract additional dependency file names
for ``moc`` from the contents of source files.

CMAKE_ANDROID_NDK_DEPRECATED_HEADERS
------------------------------------
When :ref:`Cross Compiling for Android with the NDK`, this variable
may be set to specify whether to use the deprecated per-api-level
headers instead of the unified headers.
If not specified, the default will be *false* if using a NDK version
that provides the unified headers and *true* otherwise.
