Without this, we do not cover compilation with only C++11 until nightly
testing, at which point many builds require it, and failures block
merging anything that was staged.

Qt5 supports passing function pointers to QObject::connect(), and
prefers this over SIGNAL() and SLOT(). Modernize the connections,
stop using a deprecated signal from QComboBox, and modernize a few
QKeySequence's.
Generate the same default `CMAKE_INSTALL_PREFIX` if a project is
configured with CMAKE_GENERATOR_PLATFORM (`cmake -G "Visual Studio
[...]" -A x64` and `cmake -G "Visual Studio [...]" -A ARM`) instead of
the prior CMake 3.1 way (`cmake -G "Visual Studio [...] Win64"` and
`cmake -G "Visual Studio [...] ARM"`).
The strawberry perl distribution ships a pkg-config file and a
pkg-config.bat file.
find_program() does not usually look for a .bat file program unless
explicitly specified in the NAMES argument. This would cause
CMake to find the non-bat file, and executing that with
execute_process() leads to a
'%1 is not a valid Win32 application' error.
Prefer to search for pkg-config.bat file when on a Windows host, in
additiona to the regular pkg-config file.

The new Xcode 12 build system does not support recursive
invocation. Therefore lazily triggered builds for the
corresponding platform which run during the `install` target
fail with:
```
error: unable to attach DB: error: accessing build database
```
While looking for a work-around we conditionally disable those
tests.
Issue: #21206
In commit 55196a1440 (MSVC: Use 'lib' instead of 'link /lib' to create
static libraries, 2020-01-10, v3.18.0-rc1~625^2) we changed CMake to use
lib instead of `link /lib` to create static libraries, but it didn't
search for `llvm-lib`. If you have `llvm-lib` but not `lib` (e.g. when
cross-compiling), when `CMakeFindBinutils` is invoked for the `C` and
`CXX` languages, `CMAKE_AR` is not found. When it's subsequently invoked
for the ASM language, `CMAKE_ASM_SIMULATE_ID` and
`CMAKE_ASM_COMPILER_FRONTEND_VARIANT` are not set (because
`CMakeDetermineASMCompiler` doesn't call `CMAKE_DETERMINE_COMPILER_ID`,
which sets those variables), so we go down the non-MSVC conditional and
set `CMAKE_AR` to a GNU-style `ar`, which of course does not understand
lib flags. Explicitly search for `llvm-lib` to avoid this situation.
For NVCC the compiler takes care of device linking when passed the "-dlink"
flag.
Clang doesn't support such magic and requires the buildsystem to do the work
that NVCC does behind the scenes.
The implementation is based on Bazel's device linking documentation:

The original Xcode build system did not properly re-link targets that consumed
object libraies. We worked around that with a post-build command on the object
libraries themselves that removed their consumers if out of date. The "new
build system" does not appear to need such help, so drop the workaround.
The target has not been generated since commit d92d51429e (BUG: fix for bug
6193, fix xcode depend helper, 2008-01-10, v2.6.0~553). Remove it from
the list of special targets.
Using the cublas device libraries seems to require at least sm_35.
Set the architecture explicitly to sm_35 for old CUDA versions, which still
have the cublas device library.
To avoid problems accessing filesystem, use 64-bit file offsets when
compilation model is 32-bit. This explicit definition is needed now
that KWSys does not provide LFS settings in its headers anymore.
