Fixes#17559
Replace our hard-coded default of cudart=static with a first-class abstraction to select the runtime library from an enumeration of logical names.
QCC is a wrapper around GCC, but it is not a fully transparent wrapper.
Some compile options need to be passed to GCC using a `-Wc` option.
QCC does not support --sysroot, so setting CMAKE_SYSROOT in a toolchain
file currently does not work. This means that it is likely that no one
is setting CMAKE_SYSROOT in existing QNC toolchain files. Override the
GCC option for sysroot in the QCC.cmake file with -Wc,-isysroot.
This exposes a further issue in that the QNX SDK does not follow the
same architectural folder structure as linux uses. That is, on linux
systems, architecture-specific libraries might be in
<sysroot>/usr/lib/<arch>
such as
/usr/lib/x86_64-linux-gnu/libcurl.so
CMake models this by suffixing the <arch> onto lib directories when
searching for libraries.
The QNX SDK is structured differently such that the <arch> should be
used as a prefix:
<sysroot>/<arch>/usr/lib
such as
<sysroot>/x86_64/usr/lib/libcurl.so
Add a variable for platform configuration to set whether to prefix or
suffix the <arch> and set that in the QCC.cmake.
Use the directory structure of the QNX SDK to compute the <arch> from
the implicit library directories. The assumption is that the arch will
be a single directory directly below the CMAKE_SYSROOT, below which the
usr/ prefix occurs.
It would not be appropriate to instruct users to make the <arch> part of
the sysroot when specified in the toolchain file because:
1. That would be non-DRY - The QCC wrapper already determines the <arch>
by the -V argument passed to the compiler, specified in the toolchain
file as the CMAKE_C_COMPILER_TARGET variable.
2. The includes in the QNX SDK are not below the <arch> directory.
So, the location of the <arch> in the full path is different on QNX
compared to, say an embedded linux platform, but the intent is the same.
Add documentation to recommend the use of CMAKE_SYSROOT in a QNX
toolchain file.
As the CMAKE_SYSROOT is always the same for QNX, it would be possible to
simply set it in QCC.cmake. However, that would change behavior for
existing users as when CMAKE_SYSROOT is set, files/paths outside of the
CMAKE_SYSROOT do not get found.
The <arch> prefixing is only enabled in cmSearchPath.cxx if
CMAKE_SYSROOT is set. This ensures that the user gets consistency in
the current state without CMAKE_SYSROOT, and gets better consistency
when using CMAKE_SYSROOT.
This introduces 2 new INTERFACE IMPORTED libraries: GTest::gtest and
GTest::gtest_main. They link to GTest::GTest and GTest::Main targets
respectively, therefore working as aliases. These new names map the
names of the targets from upstream GTest's CMake package config.

Using MATCHES "^${_Name}_FOUND$" limits the name of the found variable,
since it can't contain any regular expression special-chars (period,

Bring whitespace and code style up to date in these scripts. Both
scripts share the same origin but have diverged over time, so
synchronize them again. This is relevant because BLAS and LAPACK
detection is often performed simultaneously, so both scripts should
evolve in sync. While at it, update a few comments.
This update is intended to have no functional changes.
In commit fb3370b6a1 (MSVC: Add abstraction for runtime library
selection, 2019-04-10, v3.15.0-rc1~229^2) we overlooked populating the
runtime library selection flags for the Microsoft assembler. It does
not actually have any such flags, but since its compiler id is `MSVC`
our generators expect the table to be populated. Use empty values.
Without this fix, enabling the `ASM_MASM` language with policy `CMP0091`
set to `NEW` causes an error due to the missing table entries.

The change in commit 5861c6d450 (FindMPI: Preserve include order when
extracting component directories, 2019-12-19) converted a CMake-language
function to a macro. However, it contains a `return()` call that now
applies in the caller's scope, which is in correct. The `return()` is
meant to skip work when using a MPI compiler wrapper as the main
compiler. Move that condition to the call site instead.

Modern distributions of packages built with MinGW tools provide `.dll.a`
import libraries. Prefer those instead of finding plain `.dll` files.
This avoids accidentally finding unrelated Windows `.dll` files.
