Question 1

How to set up CTest with CMake for automated testing?

Accepted Answer

This project demonstrates CTest integration by including test commands in the CMake configuration; follow the README to run 'ctest' after building, which executes predefined test suites and reports results.

Question 2

CMake example vs official CMake tutorials: which is better for learning?

Accepted Answer

This example offers a hands-on, cohesive project to quickly see CMake in action, while official tutorials provide comprehensive but scattered documentation. Use this for practical insights and tutorials for deep dives.

Question 3

What is CDash and how do I use it with my CMake project?

Accepted Answer

CDash is a testing dashboard for aggregating results; this example shows configuration for submitting tests via CMake, but the linked dashboard is empty, so you'll need to set up your own server for full functionality.

Question 4

How to configure CMake for cross-platform builds on Windows and Linux?

Accepted Answer

The project illustrates multi-platform setup with installation paths, but you'll need to adapt the CMakeLists.txt for specific compiler flags and dependencies based on your target OS.

Question 5

Best practices for structuring a CMake project with multiple targets?

Accepted Answer

This demo uses modular targets for build, test, and install; study its CMakeLists.txt to see how to separate concerns, but note that real projects may require more complex hierarchies.

Question 6

Can I use this CMake example for a large C++ library?

Accepted Answer

It provides a foundational structure, but for large libraries, you'll need to extend it with features like packaging, versioning, and dependency management not covered in depth here.
