Breaks Windows builds

PiperOrigin-RevId: 210434120

Fix Theta(N^2) memory usage of EXPECT_EQ(string) when the strings don't match.

The underlying CalculateOptimalEdits() implementation used a simple
dynamic-programming approach that always used N^2 memory and time. This meant
that tests for equality of large strings were ticking time bombs: They'd work
fine as long as the test passed, but as soon as the strings differed the test
would OOM, which is very hard to debug.
I switched it out for a Dijkstra search, which is still worst-case O(N^2), but
in the usual case of mostly-matching strings, it is much closer to linear.

This makes ResultOf more convenient to use. In particular, the matcher now accepts
lambdas.

To make sure packages are relocatable, use `$<INSTALL_PREFIX>` in
`$<INSTALL_INTERFACE:...>` `target_include_directories`.

`$<INSTALL_PREFIX>` was introduced in CMake 2.8.11, which is already
being checked for locally.

Fix #1764 Remove cmake code that leads to a configuration error

This step is no longer necessary. The configuration given in the
googletest README.md is sufficient to bring in all the googlemock
headers.

Issue #1735 It seems like CMAKE_CXX_FLAGS is getting double appended when buildin…

Googletest export

Remove unneeded check for NULL.

which breaks my build as gcc does not allow -specs=nosys.specs to be called multiple times.

Removing this fixes it and seems to keep the same compile options, just removing the duplicate definition.

Install CMake export files

Rework of the closed pull request #768

Improve CMake exported targets

I _think_ this represents some of the "best practices" for exporting
targets. They'll be available in a `googletest::` namespace (e.g.
`googletest::gmock`) with non-namespaced `ALIAS` targets.

- Added GOOGLETEST_VERSION variable
- Use `CMakePackageConfigHelpers`, bump minimum CMake version to 2.8.8
