CLion fails to find some of my headers. Where does it search for them?

CLion searches through the same places CMake does. Set the include_directories variable in CMake to provide the headers path to the IDE. More details on CMake configuration can be found in our Quick CMake Tutorial.

Since CLion 1.5 EAP there is also a new feature ‘Mark Directory As’ that allows to mark directories as:

  • Excluded
  • Libraries
  • Project sources and headers

Read more about use cases and details in our blog.

I hope this helps.

cmake_minimum_required(VERSION 3.6)
project(untitled)

set(CMAKE_CXX_STANDARD 11)

#Set your directories. The dot representes the root application folder.
#Thus my the path to my domain folder:
set(APP_DOMAIN ./domain)
set(APP_CALC ./calc)

#Include the directories and now your cpp files will recognize your headers
include_directories(${APP_DOMAIN})
include_directories(${APP_CALC})

set(
SOURCE_FILES
main.cpp
${APP_DOMAIN}/person.h
${APP_DOMAIN}/person.cpp
${APP_CALC}/add.h
${APP_CALC}/add.cpp
)
add_executable(untitled ${SOURCE_FILES})

#CHEARS!

In my CMakeLists.txt I tried 

include_directories( ./src )

But still the line

#include <module.h>

is grayed out and GoTo Definition / Declaration doesn't work. When I change that to 

#include "module.h"

it does work as the .cpp file is in the same folder as the header. But I'm not allowed to use "". How do I make CLion find my headers included with #include <> ? Any help would be greatly appreciated.

I have the same issue: my header files are included as #include <xxx.h> and they are not recognised and all my struct definitions are red

I have included 

include_directories( ./src/include )
which is where my header files are

We can't reproduce the problem on our side. Could you please file a bug report and attach an isolated sample project?

Thanks in advance.

I have a project which builds inside an "SDK" in chroot environment. Project CMake build system is designed to be used from inside the SDK. I managed to build the project by specifying CMake from inside the SDK in CLion->Settings->Build,->Toolchains.

Problem is that build is working now, but proper indexing is not. CMake cache contains paths to includes relative to the SDK root. It makes make happy, but CLion can't resolve them.

Question is if there is any CLion configuration file where I can specify include paths for indexing?

V Krikun, could you please describe your configuration (and if possible, attach the generated cmake files) in CPP-2519?
