eclipse cdt - 改变项目类型

Question

I have a bunch of Eclipse projects imported into my workspace. I know how to add a directory for Eclipse to search for headers to resolve symbols.

However, some of my projects do not allow me to add these directories and I realized that it's because those projects are not the correct type.

Right click > Properties on the 'correct' type of project shows an item in the list called " C/C++ Build

If it has this entry, then in C/C++ General it has an entry called Paths and Symbols wherein I can add necessary include directories so that the indexing works.

QUESTION

How do I change the properties of this project so I can use indexing and add directories for indexing?

I've found one thing that obviously needs to be changed: in the 'correct' project, Right Click > Properties > Builders has two entries: CDT Builder and Scanner Configuration Builder while the 'incorrect' project is missing these two.

How do I add them? Import yields a blank page and New is just as useless.
