The current ctest timeout in VTK-m are fine for the CI, but are too long for develoment when a test is hanging on a queued node. This commit allows a developer to turn off the majority of the hard coded timeout values which allows them to set them at the ctest command-line.
Several revisions ago, the ability to use virtual methods in the
execution environment was deprecated. Completely remove this
functionality for the VTK-m 2.0 release.
There is a Makefile include, `vtkm_config.mk`, and a package include,
`vtkm.pc`, that are configured so that external programs that do not use
CMake have a way of importing VTK-m's configuration. However, the set of
libraries was hardcoded. In particular, many of the new filter libraries
were missing.
Rather than try to maintain this list manually, use the module mechanism
in the CMake configuration to get a list of libraries built and
automatically build these lists.
This mechanism sets up CMake variables that allow a user to select which
modules/libraries to create. Dependencies will be tracked down to ensure
that all of a module's dependencies are also enabled.
The modules are also arranged into groups.
Groups allow you to set the enable flag for a group of modules at once.
Thus, if you have several modules that are likely to be used together,
you can create a group for them.
This can be handy in converting user-friendly CMake options (such as
`VTKm_ENABLE_RENDERING`) to the modules that enable that by pointing to
the appropriate group.
The reason why we did not support shared libraries when CUDA compiles
were on is that virtual methods require a special linking step to pull
together all virtual methods that might be called. I other words, you
cannot call a virtual CUDA method defined inside a library. This
requirement goes away when virtuals are removed.
Also removed the necessity of using seprable compilation with cuda.
Again, this is only needed when a CUDA function is defined in one
translation unit and used in another. Now we can enforce that all
translation units define their own CUDA functions.
Also, suppress warnings in cuda/internal/ExecutionPolicy.h
This is where we call the thrust algorithms. There must be some loop
where it, on some code path, calls back a host function. This must be in
an execution path that never happens. The thrust version has its own
suppress, but that does not seem to actually suppress the warning (it
just means that the warning does not tell you where the actual call is).
Get around the problem by suppressing the warnings in VTK-m.

Deprecate `VirtualObjectHandle` and all other classes that are used to
implement objects with virtual methods in the execution environment.
Additionally, the code is updated so that if the
`VTKm_NO_DEPRECATED_VIRTUAL` flag is set none of the code is compiled at
all. This opens us up to opportunities that do not work with virtual
methods such as backends that do not support virtual methods and dynamic
libraries for CUDA.
As we remove more and more virtual methods from VTK-m, I expect several
users will be interested in completely removing them from the build for
several reasons.
1. They may be compiling for hardware that does not support virtual
methods.
2. They may need to compile for CUDA but need shared libraries.
3. It should go a bit faster.
To enable this, a CMake option named `VTKm_NO_DEPRECATED_VIRTUAL` is
added. It defaults to `OFF`. But when it is `ON`, none of the code that
both uses virtuals and is deprecated will be built.
Currently, only `ArrayHandleVirtual` is deprecated, so the rest of the
virtual classes will still be built. As we move forward, more will be
removed until all virtual method functionality is removed.
`assert` is supported on recent CUDA cards, but compiling it appears to be
very slow. By default, the `VTKM_ASSERT` macro has been disabled whenever
compiling for a CUDA device (i.e. when `__CUDA_ARCH__` is defined).
Asserts for CUDA devices can be turned back on by turning the
`VTKm_NO_ASSERT_CUDA` CMake variable off. Turning this CMake variable off
will enable assertions in CUDA kernels unless there is another reason
turning off all asserts (such as a release build).
