Unfortunately that didnt help. this is the current as variable and custom command

SET( _PDB_COPY_CMD 
	${CMAKE_COMMAND} -E
	copy_if_different 
	"$<TARGET_FILE_DIR:bif>/$<TARGET_FILE_BASE_NAME:bif>.pdb"
	"$<TARGET_FILE_DIR:App>/imageformats"
	)
add_custom_command( TARGET App POST_BUILD 
    COMMAND $<$<CONFIG:Debug,RelWithDebInfo>:${_PDB_COPY_CMD} >
    DEPENDS bif
    COMMENT "ADDING BIF Image Format Shared Library PDB file Library"
    )

and this is the generated output from the vcxproj
