This fixes several reported bugs about CMake not handling
non-ascii paths on Windows.
Practically, the use of some unicode characters may still
be limited by the build or compiler tools.
For example, a user may be limited by the build tools to
using characters within the Windows ANSI code page (which can
include non-ascii characters in the current system language).

AppleClang does not support the cxx_thread_local feature, even
though it is based on a Clang version which does support the
feature.
http://stackoverflow.com/a/23850891/2428389
A possible reason for that is that thread_local might be used as
a variable in existing Apple SDK headers.
Extend the WriteCompilerDetectionHeader module to generate a define
for that feature with portability fallbacks. For the avoidance of
making it easy to write code which looks correct but which has odd
runtime behavior, don't set the define symbol at all if no
equivalent keyword is known.

b341799e Tests: Fix RunCMake.CompileFeatures test NonValidTarget2 case
On OS X, when CMAKE_USE_OPENSSL is OFF, use the OS implementation.
This will allow the OS-configured CA list to be trusted automatically.
This is supported on OS X 10.6 and above using AppleClang, Clang, and
GNU compilers.
Also add a 'CMAKE_ANDROID_API_MIN' variable to set the property
default. Teach the VS generator to write the MIN API value into
Nsight Tegra project files.
When install(EXPORT) is given an absolute destination we cannot compute
the install prefix relative to the installed export file location.
Previously we disallowed installation of targets in such exports with a
relative destination, but did not enforce this for target property
values besides the location of the main target file. This could lead to
broken installations when the EXPORT is installed to an absolute path
but usage requirements are specified relative to the install prefix.
Since an EXPORT installed to an absolute destination cannot be relocated
we can just hard-code the value of CMAKE_INSTALL_PREFIX as the base for
relative paths. This will allow absolute install(EXPORT) destinations
to work with relative destinations for targets and usage requirements.
Extend the ExportImport test with a case covering this behavior.
If this option is enabled, the test step is created with the
EXCLUDE_FROM_MAIN option, and if TEST_BEFORE_INSTALL is enabled, the
install step does not depend on the test step.
This means that the test step is never executed, unless the test target
is explicitly created by calling ExternalProject_Add_StepTarget, or by
passing it with the STEP_TARGETS option, or with the EP_STEP_TARGETS
directory property.
Copy CMAKE_EXE_LINKER_FLAGS into the test project generated by
try_compile, just like we already copy CMAKE_<LANG>_FLAGS.
Add CMake Policy CMP0056 to activate this behavior in a compatible way,
but do not warn by default when the policy is not set since it will
affect all try_compile calls.
Extend the RunCMake.try_compile test with a case covering this behavior
for each policy setting.
With PushScope and PopScope, keeping track of another bit of data for
each scope isn't easy. Instead, store it as another CMake variable so it
gets implicitly tracked along with everything else.
This works in a revert of commit
7d674b5f0b.
In commit 079e8469ab (... OpenGL always needs X11 on Unix, 2002-09-05)
the FindOpenGL module was taught to search for X11 as a dependency of
the OpenGL library. This was done without a detailed explanation, and
the dependency should not be explicitly needed because OpenGL headers
should not expose applications to X11 APIs directly.
Unfortunately the only way to know if anything legitimately depends on
this behavior (perhaps in static library cases) is to simply remove it
and wait for issues to be reported. If so, then we can add some kind of
compatibility setting for this later. Add a release note to draw
attention to this change.

Some applications only need the OpenSSL crypto library and want to avoid
linking against the SSL library. Set OPENSSL_CRYPTO_LIBRARY and
OPENSSL_SSL_LIBRARY in the code paths that do not need to find them
separately, and document them publicly. This allows applications to be
more specific when linking against OpenSSL.
