Hi,
I’m thinking about adding a new generator expression to make it easier to collect the directory necessary to find all dlls, and to use it then e.g. to generate a bat file or to set the VS_DEBUGGER_ENVIRONMENT target property.

What do you think ? Comments ?

Sure, I think that makes sense. It would be in a similar vain to the $<TARGET_RUNTIME_DLLS> genex.
Should I filter out some default directories, because they are searched anyway ? If yes, I guess there’s some cmake variable which contains those system directories ?
No, let’s just have it add the directory for every entry in $<TARGET_RUNTIME_DLLS>. Maybe we could filter out duplicates.
Ok, the code in the branch already skips duplicates.
Is TARGET_RUNTIME_DLL_PATHS a good name, or would TARGET_RUNTIME_DLL_DIRS be better ?
Or some other name ?
Your suggestion is exactly what I was looking for reading up the generator expressions available to populate VS_DEBUGGER_ENVIRONMENT on test executables. 
Can’t wait to see this in a release!
(Regarding names, I like the suggested TARGET_RUNTIME_DLL_PATHS)
It should be in 3.27, TARGET_RUNTIME_DLL_DIRS.
