How to include C++ headers with a library name using CMakeLists.txt?

I have C++ source code in following hierarchy

main.cxx
CMakeLists.txt
someDirectory/myClass.cxx
someDirectory/myClass.h

My CMakeLists.txt is as follows

cmake_minimum_required(VERSION 2.8)
project(cmakePjt)
include_directories(someDirectory)
add_executable(cmakePjt main.cxx)

My main.cxx includes myClass as follows

#include "myClass.h"

And the above works! But I want to include myClass in my main.cxx as follows and how should I change my CMakeLists.txt for that?

 #include "myLibName/myClass.h"

There is nothing CMakeLists can do. You have to actually create an existing actual directory with the name myLibName, move the .h file to that directory, and add the containing directory of that directory to include the search path.

Your project may look for example like this:

main.cxx
CMakeLists.txt
myLibName/src/myClass.cxx
myLibName/include/myLibName/myClass.h
myLibName/CMakeLists.txt

Where:

# myLibName/CMakeLists.txt
add_library(myLibName src/myClass.cxx)
target_include_directories(myLibName PUBLIC ./include)

# CMakeLists.txt
add_subdirectory(myLibName)
add_executable(cmakePjt mina.cxx)
target_link_libraries(cmakePjt PRIVATE myLibName)
