Including directories in Clion

Question

Whenever I wanted to include a directory that was located outside of my project with Clion I would use the -I somedir flag. This time however, what I want to do

Answer 1

Command INCLUDE_DIRECTORIES doesn't add any source file for compile!

Instead, this command defines directories for search header files.

You need to list all source files in add_executable() call in any case:

include_directories(src)
set(SOURCE_FILES
    src/Dijkstra/Dijkstra.cpp
    src/Graph/Graph.cpp)
add_executable(someprojectname ${SOURCE_FILES})
