similar to other bug, bug a bit different QTCREATORBUG-23128

 from the source_group documentation https://cmake.org/cmake/help/latest/command/source_group.html

a project with `source_group(TREE ${CMAKE_CURRENT_SOURCE_DIR})` should have the same effect as manually defining the tree structure. But currently with QtCreator 4.11-RC1 we get a group named TREE with all the files in it

 cmake
 cmake_minimum_required(VERSION 3.15)
 project(folderstructure)
 set(files
 src/a/file_a.cpp
 src/b/file_b.cpp
 include/a/file_a.h
 include/b/file_b.h)
 add_library(l1 SHARED ${files})
 target_include_directories(l1 PUBLIC include)
 source_group(TREE ${CMAKE_CURRENT_SOURCE_DIR})

expected structure

• l1
  • src
    • a
      • file_a.cpp
    • b
      • file_b.cpp
  • include
    • a
      • file_a.h
    • b
      • file_b.h

what we actually get

• l1
  • TREE
    • file_a.cpp
    • file_a.h
    • file_b.cpp
    • file_b.h
