Support for C11's _Thread_local was introduced in GCC in the 4.9 series,
even though we make the C11 compiler flags available in CMake with GCC
>= 4.6.
FreeBSD's runetype.h uses _Thread_local, which causes CMake's own build
to fail when using GCC < 4.9 and -std=gnu11:
/usr/include/runetype.h:92:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'const'
extern _Thread_local const _RuneLocale *_ThreadRuneLocale;
Add a test for _Thread_local support and only build CMake itself with
C11 support if it works.

Refactoring in the topic merged by commit v3.2.0-rc1~400 (Merge topic
'refactor-search-path-construction', 2014-11-13) introduced a bug that
filters out duplicate paths in an incorrect order. Restore the search
path to its documented order even when duplicate paths are present.

With 64-bit Windows builds, there is no need to remove the leading
underscore from all the symbols. This is because it does not have one
in the .obj file unless it is really in the name. This did not cause
any trouble until VS 2015 which has some system functions that have a
leading underscore that end up in the .def file.
This is needed for proper makefile progress tracking.
The cmLocalGenerator is constructed at configure-time, but only used
at generate time. The StateSnapshot member is currently populated
before configuring, so use the Makefile to get the end snapshot.
This is the appropriate snapshot for future use. Existing users
of this method are mostly just calling GetDirectory on the result,
but the progress tracking of the Makefile generator needs a consistent
snapshot to be used, so the end snapshot should be consistently used.
The calls to find_program now use NAMES_PER_DIR so that the first executable
(e.g. h5pcc) appearing on their PATH will get chosen. The HDF5_PREFER_PARALLEL
variable swaps the search order when it is set to true in the event that a
directory being search contains both h5cc and h5pcc.
When compiling with
LDFLAGS='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld'
the compiler output includes a line like
COLLECT_GCC_OPTIONS='-specs=/usr/lib/rpm/redhat/redhat-hardened-ld' ...
that our link line regex matches due to an argument ending in "-ld".
Since it is not really the link line no implicit link information is
dectected. Exclude "VAR=..." lines from consideration as link lines to
fix this.
Extend the RunCMake.set_property test with cases covering buildsystem
directory properties:
* COMPILE_DEFINITIONS
* COMPILE_OPTIONS
* INCLUDE_DIRECTORIES
Also test a non-buildsystem property to document the equivalence
in behavior.
This is a change in behavior from CMake 3.3, but there is no semantic meaning
to empty entries in buildsystem properties. This also restores behavior to
that of CMake 2.8.10.

RtlGetVersion is a private API not meant for public use. Another
solution to detecting the Windows version will be needed.

Since commit v3.1.0-rc1~635^2~7 (project: Add infrastructure for
recording CXX compiler features, 2013-10-17) we compile a test source to
a binary and then extract "<LANG>_FEATURES:..." strings from the binary
with the file(STRINGS) command. Add a newline at the beginning of the
string literal to be sure file(STRINGS) can extract the first entry as a
string independent of whatever else the compiler may put before the
storage it allocates for the literal within the binary.
