Summary:                    CMake cannot detect changes in nested header files
when using '-iquote'
Description: 
Create a new project with such CMakeLists.txt:

cmake_minimum_required(VERSION 3.3)
project(test)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -iquote ${CMAKE_CURRENT_SOURCE_DIR}")
add_executable(test-iquote main.cpp dir/1.h dir/2.h)

And such structure:

CMakeLists.txt
Main.cpp          (contains #include "dir/1.h")
dir\
    1.h           (contains #include "dir/2.h")
    2.h

Build. Then modify 2.h. Build again. Nothing will happen, it will just say
'[100%] Built target test-iquote'. 

Additional Information: 
Tried with both clang and GCC. GNU Make 3.81.
