Bump `cmake_minimum_required` to 3.5.

Delete conditional branches exclusive to older versions.

Notable dependents:
  - github.com/grpc/grpc >= 3.5.1
  - github.com/abseil/abseil-cpp >= 3.5
  - github.com/googleapis/google-cloud-cpp >= 3.5

On the other hand, github.com/protocolbuffers/protobuf is >= 3.1.3, but it only depends on GoogleTest 1.10.

Fixes #3523

Remove scripts for code generating together with related files.

PiperOrigin-RevId: 352805926

Rollback change from
https://github.com/google/googletest/pull/1836. This change generates
a script on Windows to actually run each test, but the script itself
doesn't correctly report if the test passed.

This change will "break tests" that were already broken on Windows,
but weren't being reported as such.

Move matchers' tests from *generated* to common files.

When building packaged shared libraries for use, having the version
set makes it so that the soname is set correctly for parallel installation.

This change is derived from the one used for the Fedora gtest package.

Clarify build system support - CMake and automake community supported

PiperOrigin-RevId: 245821927

Building all test binaries under their respective subtrees makes
building the project via cmake easier to grok without additional hacks.
In particular, when dealing with the conversion I proposed in
https://reviews.freebsd.org/D19430

 (switching from autotools to cmake),
I ran into unexpected gtest prefixing under the googlemock directory, as
opposed to the googletest directory. Example:

Before: `googlemock/gtest/googletest-break-on-failure-unittest_`
After:  `googletest/googletest-break-on-failure-unittest_`

The latter form is easier to translate to packaging manifests when
building googlemock is disabled, as well as enabled, as the path remains
consistent when the feature flag is disabled.

Internal Change

PiperOrigin-RevId: 212656679

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.

Rework of the closed pull request #768

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

Change location of generated pkg-config files from CMAKE_BINARY_DIR to gmock/gtest_BINARY_DIR (#1717)

Fix double free when building Gtest/GMock in shared libraries and linking a test executable with both.

change static_cast to ImplicitCast_ for consitency
fixes for building with path names containing spaces

If the user's cmakelists.txt first look for threads using
find_package(Threads), then set(gtest_disable_pthreads ON),
and then include googletest. GoogleTest will not look for
threads. But since they have already been found before in
user's cmakelists, it will use them regardless.

This helped me fix build issue in darktable-org/rawspeed
on windows/MSYS2, even though there are threads, and they
are usable, googletest build was failing with issues
about AutoHandle. I was first looking for threads, and only
then including googletest, so no matter the value of
gtest_disable_pthreads, it failed.

The other obvious solution is for user to first include
googletest, and only then look for threads by himself.

Modify library install destinations to install .dll's to the correct
location (`bin`, not `lib`), and to install other artifacts to the
correct platform-dependent location by using GNUInstallDirs. This is
required for some distributions (e.g. Fedora) and will fix an issue that
otherwise requires those distributions to patch the upstream sources.
Also, add options to suppress installation, which may be useful for
projects that embed Google Test.

Since Google Test is trying to support archaic versions of CMake, a
brain-dead fallback (which requires that the user set either LIB_SUFFIX
or CMAKE_INSTALL_LIBDIR themselves) is included for versions that
predate GNUInstallDirs.

Fixes #1161.
