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.
The FindXerces module was added in commit v3.1.0-rc1~155^2 (FindXerces:
New module to find Apache Xerces-C++, 2014-08-17). However, there are
two implementations of Xerces, one in C++:
http://xerces.apache.org/xerces-c/
and one in Java:
http://xerces.apache.org/xerces-j/
Rename FindXerces to FindXercesC to clarify that it is about the C++
implementation.
While at it, add the missing CMake 3.1 release note about this module.

When compiling the ABI detection test project, do not override
CMAKE_EXE_LINKER_FLAGS completely. The normally selected value of this
variable may influence how the link is done and may be needed to be
representative of how the calling project will be built. Instead pass a
variable that try_compile will reference as additional flags. Leave
this behavior of try_compile undocumented for now.
Revert the feature added by commit v3.1.0-rc1~420^2~2 (FindOpenGL:
Provide imported targets for GL and GLU, 2014-05-31). Unfortunately it
does not work on Windows because the full path to each library file is
not actually known. The IMPORTED_LOCATION of an imported target must be
a full path, but OPENGL_gl_LIBRARY is just 'opengl32' on Windows because
the actual library file is in some implicit link directory that we may
know know.
More infrastructure will be needed in CMake to allow a name-only
imported library. Until that exists, we will not be able to provide
imported targets in FindOpenGL.
In commit v3.1.0-rc1~640^2~5 (Clean up usage of if(... MATCHES regex)
followed string(REGEX REPLACE regex), 2014-04-06) we accidentally broke
logging of the implicit library detection. Restore use of the
intermediate 'lib' variable so that the log message is constructed
properly.

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.
f327a9fd Merge branch 'default-lang-dialect' into step2
36bb100e Fix the test for running the CxxDialog unit test.
a3d0ae17 Features: Fix the default C dialect for Clang and GNU.
49e2b689 Features: Fix references to CXX compiler version in Clang-C.cmake.
7565ab2c Features: Test the CXX compiler only if it has features.
These all test the same variable for different values, so only one of them can
ever be true. This also allows to completely remove one variable that only
flagged if one of the conditions matched.
The __STDC_VERSION__ macro may be defined or not depending on the
implementation dialect of C. Test that it is defined before testing
its value.
The CXX tests do not need such a change because they define __cplusplus
in all dialects.
Extend the write_compiler_detection_header interface to allow
specifying a location for supplementary files, and getting the
list of resulting files as a variable.
Clang 3.4 uses C99 by default, and Clang 3.6 uses C11 by default:
http://thread.gmane.org/gmane.comp.compilers.clang.devel/39379
GNU 4.9 uses C90 by default, and GNU 5.0 uses C11 by default:
https://gcc.gnu.org/gcc-5/changes.html
Test that the default compiler settings result in the expected dialect
macros being defined for both C and CXX. Remove the unused main.c
file from the CompileFeatures unit test.
