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).
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.
