Making the script more complex

In this section, we will show you a more complex script that includes subfolders, libraries, and executables, all in only two files and a few lines, as shown in this script.

It's not mandatory to create multiple CMakeLists.txt files because we can specify everything in the main CMakeLists.txt file. It is more common to use different CMakeLists.txt files for each project subfolder, making it more flexible and portable.

This example has a code structure folder that contains one folder for the utils library and the other for the root folder, which contains the main executable:

CMakeLists.txt
main.cpp
utils/
  CMakeLists.txt
  computeTime.cpp
  computeTime.h
  logger.cpp
  logger.h
  plotting.cpp
  plotting.h

Then, we need to define two ...
