Either close all projects you do not want to compile (right click on open project, and select close project, then the build and debug buttons will only work on the open projects,. Alternatively, right click on the project you want to compile and click build project.

You can also select Project -> Build Project in the menu to compile the project containing the file your cursor is in. Bind it to Ctrl+B if you want.
