Previously, multi-config generators were detected by the value of the
CMAKE_CFG_INTDIRvariable. If a multi-config generator was detected, the CMAKE_CFG_INTDIR was included.This has different values from the $ generator expression into which the ExternalUtil.hpp file is generated for each configuration.
This change uses
CMAKE_CONFIGURATION_TYPESfor multi-config generator detection and provides a more robust dependency handling for the generated files. Additionally it uses the$<CONFIG>generator expression to set the include directory for multi-config generators.Closes #3314
