[CMake] add_test WORKING_DIRECTORY option

[David Cole]

What is the cwd when your test starts?

It should be ${Bwr_Dir} according to your email's WORKING_DIRECTORY arg.
(write a little code that prints it out right at the top of the
program's main before doing anything else...)

What version of ctest is this? (I assume 2.8.4?)

It sets the WorkingDirectory in the process execution data structures
before launching the process. How this translates into process
launching behavior varies from platform to platform, but it should be
working essentially the same way as what you suggest.


Perhaps: are you also setting the WORKING_DIRECTORY test property? Is
that being set to a different value?
