This is related to DynamoRIO/dynamorio#1392 and boils down to the usage of CMAKE_BUILD_TYPE in the configuration step. The hack which is done in the DynamoRIO cmake script clashes with our generator expression based build-type handling.

We keep that as a known limitation, as it only affects the following scenario:

• Use of Visual Studio generator
• and building in Debug mode (all other modes are not affected).
• and build-type is not set at configure time (or is set to other type than used at compile time)

Workaround

• Use Ninja generator (cmake -GNinja ..)
• Use VS generator and set CMAKE_BUILD_TYPE to the same as used at compile time.
