Using cmFileTime to store and compare file times in cmDependsC allows us to
read the cache file modification time only once instead of over and over again
for each comparison.
After the switch to `cmFileTime`, the anonymous private class of
`cmFileTimeComparison` held only a `std::map`. This moves the
`std::map` to the `cmFileTimeComparison` class itself and removes the
instantiation of an anonymous private class.
This replaces OS dependent code in `cmFileTimeComparison` with `cmFileTime`
instances that provide the required file time load and comparison operations.
A new public `cmFileTimeComparison::Load` method is introduced that,
for a given file name, updates the `cmFileTimeComparison` cache on demand and
returns a `cmFileTime` instance on success.
The new cmFileTime class stores the file modification time as an OS independent
nanosecond count. Its main use is to load and compare file modification times
in nanosecond and second resolution.
Replicate behaviour of upstream GLEW.
* define the imported target GLEW::glew for the shared library GLEW
* if GLEW_USE_STATIC_LIBS is defined and set to TRUE, this module instead
defines the imported target GLEW::glew_s for the static library GLEW
* an imported target GLEW::GLEW is created as a copy of either GLEW::glew
or GLEW::glew_s
* by setting GLEW_VERBOSE you print out the log of the module.

When GIT_SHALLOW is used, the '--depth 1 --no-single-branch'
arguments are add. It means that only branch names and tags
is downloaded to repository. Most Commit Hash is not working.
With this commit the documentation was updated, to describe
the limitation of GIT_SHALLOW.

The user package registry populated by the `export()` command causes
side effects outside the build and source directories. Such effects
should be opt-in rather than op-out. Introduce a policy to change
default behavior of `export(PACKAGE)` to do nothing.
Our nightly and release binaries build in an environment that does not
support these instructions. Disable them everywhere for simplicity
because CMake's application of this library is not performance-critical.
Since commit c76c1ea208 (find_program: Consider CWD only for paths with
separator, 2018-05-31, v3.13.0-rc1~413^2) we accidentally convert the
leading `//` to just `/` on results with Windows network paths.
This was caused by `CollapseCombinedPath` being less robust than
`CollapseFullPath`. Restore use of the latter but in a way that
preserves the requirement of the above commit to support candidates that
are themselves absolute.
