Finding the toolkit is required for Clang and is assumed to have been correctly
found by FindCUDAToolkit if the CUDA language is found.
Error out early with an useful error instead of failing later on due to the
path not being set.
version.txt is gone from CUDA 11.1 installations, but the rest is the same.
Instead of looking for version.txt look for <CUDA path>/nvvm/libdevice, which
is the main thing that Clang requires (though it also checks for the existence
of bin and include).
Fixes#21353.
Revert commit a064b18f85 (FindGTest: Allow either "Debug" or "Release"
configurations., 2020-06-29, v3.19.0-rc1~584^2). If both configurations
are found then `GTEST_LIBRARY` is populated in a way that breaks
`__gtest_determine_library_type`, and the imported target is not
created correctly.

Revert commit 74b1c9fc8e (Explicitly specify language flag when source
LANGUAGE property is set, 2020-06-01, v3.19.0-rc1~722^2) and the lookup
tables from its two immediate ancestors. The purpose of that change was
to convert an explicit `LANGUAGE` source file property into an explicit
language specification compiler flag like `-x c`. This seems reasonable
since the property is documented as meaning "indicate what programming
language the source file is". It is also needed to help compilers deal
with non-standard source file extensions they don't recognize.
However, some projects have been setting `LANGUAGE C` on `.S` assembler
source files to mean "use the C compiler". Passing `-x c` for them
breaks the build because the `.S` sources are not written in C. These
projects should be updated to use `enable_language(ASM)`, for which
CMake often chooses the C compiler as the assembler when using
toolchains that support it (which would have to be the case for projects
using the approach).
Revert the change for now to preserve the old behavior for such projects.
We can re-introduce it with a policy in a future version of CMake.

The gmock libraries are referenced by GTest's CMake package files.
While at it, also explicitly install gettext. It is installed already,
but make it explicit for future testing of the FindGettext module.
(cherry picked from commit 585cc7c930)
When targeting a platform that supports multiple architectures, Xcode
may choose to build all of them in our small compiler id project.
Update the regex we use to extract the path to the compiler from
the Xcode output to account for this.

In commit b6c60f14b6 (macOS: Default to arm64 architecture on Apple
Silicon hosts, 2020-09-28, v3.19.0-rc1~63^2) we forgot to update the
compiler id architecture selection added by commit 26673bf480 (Xcode:
Explicitly specify default native architecture on macOS, 2020-07-16,
v3.18.1~20^2).

Many environment variables were documented late and got
assigned wrong versions by the script.
(The whole Help/envvar section was only added in 3.10).
