[CMake] behaviour of CMAKE_INCLUDE_CURRENT_DIR ?

[Alexander Neundorf]

Hi,  
  
how does  CMAKE_INCLUDE_CURRENT_DIR behave ? 
 
Let's say I do  
SET(CMAKE_INCLUDE_CURRENT_DIR ON) 
 
in my toplevel src/CMakeLists.txt. 
 
If a src/sub1/CMakeLists.txt contains 
 
add_executable(hello main.cpp) 
 
src/sub1/ will be part of the include path. 
 
 
But what happens in the following case: 
 
Until now there was 
 
# apply for all subdirs 
include_directories(${CMAKE_CURRENT_SOURCE_DIR}) 
 
add_subdirectory(bar1) 
add_subdirectory(bar2) 
add_subdirectory(bar3) 
add_subdirectory(bar4) 
 
I guess in this case the include_directories() command has to stay ? 
 
Bye 
Alex
