Exporting without installation
How can we make the targets of project A available to the consuming project, B? Usually, we’d use the find_package() command, but that requires creating a package and installing it on the system. While useful, this approach involves some work. Sometimes, we just need a quick way to build a project and make its targets available for other projects.
One time-saving method is to include in project B the main listfile of A, which already contains all the target definitions. However, this file might also include global configuration, CMake commands with side effects, additional dependencies, and perhaps unwanted targets for B (like unit tests). So, this is not the best approach. Instead, we can provide a target export file for the consuming project, B, to include with the include() command:
cmake_minimum_required(VERSION 3.26.0)
project(B)
include(/path/to/A/TargetsOfA.cmake)
This will define all targets of A with the correct properties...
