Using common C ++ code using the Chrome browser as an example

I think it is no secret to anyone that the new browser from Google is an open-source product written in C ++. Everyone can download its source code in C ++ and build their own browser from them.
And today I met an interesting article Code Reuse in Google Chrome Browser . There the author analyzed the use of common open-source code in this Google project and found it excellent. He found at least 26 different libraries used in this project and described them all in one table ...
I decided to first translate this table into Russian, because it can be useful to all developers in C ++ - there are many really useful open-source libraries. But this table is so simple that the translation would be meaningless - everyone can easily figure it out.
Many of these libraries will be useful not only to Web developers.

And how many open-source libraries are used in your projects? And what is the attitude guide to open-source?
At the previous place of work, we used several such libraries - zlib, LuaPlus, TinyXml, CppUnit, libraries for working with graphics (such as libpng), etc.
And in the new work, the attitude towards open-source is negative and almost nothing from open-source is used - everything is written from scratch.
