To what extent was the automatic project build process implemented at your previous workplace?

At my previous job, the project build process was highly automated. Build systems such as CMake or Make were used, which allowed dependencies and build steps to be described in configuration files.

Automation included:

• Automatic build trigger upon source file changes.
• Integration with version control systems to trigger builds on commits.
• Use of CI/CD systems (e.g., Jenkins, GitLab CI) for automatic building and testing after each change.

A simple Makefile example:

all: app

app: main.o utils.o
	g++ -o app main.o utils.o

main.o: main.cpp
	g++ -c main.cpp

utils.o: utils.cpp
	g++ -c utils.cpp

clean:
	rm -f *.o app

This approach significantly reduced manual labor and errors, speeding up the development cycle.
