When CMP0003 was first introduced we wanted to link all libraries by
full path. However, some projects had problems on platforms where
find_library would find /usr/lib/libfoo.so when the project really
wanted to link to /usr/lib/<arch>/libfoo.so and had been working by
accident because pre-CMP0003 behavior used -lfoo to link.
We first tried to address that in commit v2.6.0~440 (Teach find_library
to avoid returning library paths in system directories, 2008-01-23) by
returning just "foo" for libraries in implicit link directories. This
caused problems for projects expecting find_library to always return a
full path. We ended up using the solution in commit v2.6.0~366 (...
switch library paths found in implicit link directories to use -l,
2008-01-31). However, the special case for libraries in implicit link
directories has also proven problematic and confusing.
Introduce policy CMP0060 to switch to linking all libraries by full path
even if they are in implicit link directories. Explain in the policy
documentation the factors that led to the original approach and now to
this approach.
If the host flags contain a c++11 flag (at least for gcc), then we can't
automatically propagate to nvcc it using -Xcompiler. This is because
nvcc can't use any C++ only flags. Instead we find this flag and add it
to nvcc's flags (it has a special flag for dealing with c++11 code) and
remove it from the host flags.

Revert commit 82c51a8a (liblzma: Disable XL compiler optimizations in
one source to avoid crash, 2015-04-02) and instead add a compiler flag
to disable optimizations in every source of liblzma. Somehow the XL
compiler optimizations create incorrect behavior in liblzma and lead
to crashes or truncated output during compression.
This is for consistency with other CMake access interfaces such as
definitions and properties which use a null value as a 'not present'
value. It is source compatible with existing callers, and it returns
a pointer into actual real cache entry storage.
Prefix test commands with the CROSSCOMPILING_EMULATOR property
for target executables. This allows test suites to be run on the host
when crosscompiling.
If the CMAKE_CROSSCOMPILING_EMULATOR variable is defined, and
CMAKE_CROSSCOMPILING is TRUE, then use CMAKE_CROSSCOMPILING_EMULATOR to run
the try_run executables. This prevents the need to populate
TryRunResults.cmake when cross compiling.
This topic was never tested without some follow-up commits. The
GetCacheEntryValue API returns a pointer to memory freed on return.
It will have to be revised along with the rest of the original topic.

Add CROSSCOMPILING_EMULATOR target property for executables. This is used by
subsequent patches to run exectuables created for the target system when
crosscompiling. The property is initialized by the
CMAKE_CROSSCOMPILING_EMULATOR variable when defined.
Some tests may need to read "cmake --build" output passed through from
native build tools and do not know if it will be on stdout or stderr.
Optionally use the same variable for the execute_process output so
that it merges them and we can always match using expected stdout.
VS 2013 originally claimed to support initializer lists but a bug was
found in which it generated bad code silently. For this reason we
previously considered support to not be present. However, Update 3 adds
a hard error on cases that previously generated bad code, so it is now
safe to use initializer lists with VS 2013 Update 3 or greater. At
worst a compiler error will be issued in the cases that do not work, but
that is no different from any other compiler-specific workaround a
project code may need.
The only reason this failed to compile on VS 2013 was because the
compiler uses different initializer_list constructor argument types than
our dummy implementation. The standard does not specify the non-default
constructor argument types for initializer_list. Use a template to
match any two-arg constructor a compiler might select (e.g. begin/end or
begin/len). Use #error to preserve the error on VS 2013.
