Thyra: build failure on MSVC due to use of Scalar type
Created by: mplooster
Found while working on #1160.
Sometime in the last month a change in the Thyra code led to these build failures on Windows Visual Studio 2015. Apparently, it has issues with the Scalar type.
Thyra isn't terribly critical right now for #1160 (it was only being built as an optional package), so I will just turn it off and continue my work. I'm mostly creating the issue to let @trilinos/thyra know about it and in case it needs to be revisited in the future. Hopefully it will clear up as Thrya development continues, but if it doesn't we at least know a rough time frame of when the code that caused this build failure changed.
