How did you obtain builds? Have you ever built manually? What is the difference between a debug build and a release?

I received builds in various ways: through CI/CD systems (Jenkins, GitLab CI), and sometimes manually, especially in the early stages of the project or during debugging.

Manual build usually involves running a build script or command in the terminal, for example, mvn package for Maven or gradle build.

The difference between debug and release builds:

• Debug build contains debug information, symbols for debugging, and is not optimized for speed or size. It allows developers and testers to catch errors and view call stacks.
• Release build is optimized for performance and size, with debug information usually absent or minimal. It is used for releases and distribution.

Example: in C++, debug builds include the -g flag, while release builds use -O2 or -O3 for optimization.
