create one CmakeList.txt file for multiple subdirectories each containg its own src(.cpp files) and include(.h files)

Question

How to write one Cmake file that compile all my sub-directories each with its own executable?

       /Project
            Cmakelist.txt
            /project 1
                /src
                  .cpp
                /include
                  .h
            /project 2
                /src
                  .cpp
                /include
                  .h

@SergeyA I am newbie in Cmake, I have come across add_subdirectory, but don't know how to set the executable for each project — M.H, Apr 26 '16 at 16:34
Every subdirectory will have it's own CMakeLists.txt, with own `add_executable`. — SergeyA, Apr 26 '16 at 16:55
@Sergey I did as you said, I am getting error that I cant include_directories(include) multiple times, what should i do, beside then renaming the include folder in each project differently — M.H, Apr 26 '16 at 17:43

Include this in every CmakeList.txt subfolder

cmake_minimum_required(VERSION 3.5.2)
project(project1)
set(SRC "src/name.cpp" "include/name2.h")

add_executable(project1 ${SRC})
target_include_directories (project1 PRIVATE include)

And this in the CmakeList.txt root directory

cmake_minimum_required(VERSION 3.5.2)
project(project)
add_subdirectory(project1)
add_subdirectory(project2)

...add more if you want

you can also delete the header files from set, it will also work

create one CmakeList.txt file for multiple subdirectories each containg its own src(.cpp files) and include(.h files)
