Previously, the vtkm_unit_tests CMake function added a "NONE" argument
to the test when no device was specified. However, the correct thing to
do is to add no argument. Fixed this so that strict parsing of the test
arguments works.
Consumers of VTK-m when enabling of dropping of unused functions
will see VTK-m functions dropped. Previously this didn't happen
as VTK-m didn't build object files with the correct flags for this.
By allowing the linker to remove unused symbols we see a significant
saving the file size of VTK-m tests, examples, and benchmarks.
An OpenMP build of the tests and benchmarks goes from 168MB to
141MB which is roughly a 16% filesize reduction.
Initially I had presumed that these changes would increase link times.
But in measurements the total wall time for compilation of VTK-m has
stayed about the same ( seeing a decrease of 1.5% ). Presumably the
increased computation is offset by the reduction in file writing.
Instead of having to be called for each target you can now
pass multiple targets at once. Do note that if you pass multiple
targets you will need to pass all the sources from those targets
that need to be 'device' compiled.
This is a work around while we wait on requiring CMake 3.15 for all
cuda builds. At that point we can replace this with setting
`requires_static_builds` as part of the EXPORT_PROPERTIES of the
vtkm_cuda target.
This has been tested with the ascent proxy

This was causing issues for downstream users of VTK-m as it exposed
a bug in CM ( cmake#17952 ) where it was evaluating against the set of
enabled languages instead of possible languages.
When both examples and tests are on, there are a few tests created that
will install VTK-m and build the example against the install to make
sure that all expected components are installed. Since it requires the
full compile of a VTK-m application (and some VTK-m applications can
take a while to compile), increase the timeout for these tests.
The timeout is currently set to 10 minutes (600 seconds).

The VTK-m testing infrastructure isn't public facing so it doesn't
need to be installed or clutter the main VTKmWrappers file.
At the same time I have refactored the code to make it clearer
to understand, and remove unused options.
We want the option name to be clear that it might be applicable for
more than just CUDA. If VTK-m ever supported something like SYCL
it would not be clear that those sources should go in `WRAP_FOR_CUDA`.
The cpu architectures mode to -march is a better approach as it
maps to a more complete side of optimization flags. This makes
it easier going forward for VTK-m to support new CPU ISA's.
Previously an installed version of VTK-m wasn't relocatable as
it had system MPI paths. Additionally the installed vtkm_diy target
would depend on MPI but not `find_package(MPI)`

It is very easy to cause ODR violations with DeviceAdapterTagCuda.
If you include that header from a C++ file and a CUDA file inside
the same program we an ODR violation. The reasons is that the C++
versions will say the tag is invalid, and the CUDA will say the
tag is valid.
The solution to this is that any compilation unit that includes
DeviceAdapterTagCuda from a version of VTK-m that has CUDA enabled
must be invoked by the cuda compiler.
When you install pyexpander with pip under python 3, the executable
script is now named expander3.py instead of expander.py. Support using
either file.
We now have a couple of the examples also being built against
the installed version of VTK-m as a test. This allow us to verify
that VTK-m installs and can be found properly.

Previously we didn't realize that the cmake_install.cmake files
would properly walk the entire install tree. Therefore we would try
to find each one manually and invoke it. This caused problems with
dirty continuous build directories, and was actually unneeded as
just including the root cmake_install.cmake is sufficient.
In certain circumstances (currently, when logging is enabled), VTK-m
libraries depend on the threading library. However, when the VTK-m
package was included from an external project, it did not automatically
find the threads package. This change makes the Threads library loaded
when the VTK-m package is found.
The purpose of the TestBuild infrastructure was to confirm that
VTK-m didn't have any lexical issues when it was a pure header
only project. As we now move to have more compiled components
the need for this form of testing is mitigated. Combined
with the issue of TestBuilds causing MSVC issues, we should
just remove this infrastructure.
