CSS in a Flex 3 Library

I've made a library in flex with different components and my CSS I want to use in different projects (the goal of a library....).

BUT even if I can use my components, I can't use my CSS file which is in the library.

When 开发者_JS百科I try <mx:Style source="assets/style.css" />, it wasn't found :(

So, how I should do to have a CSS file in my library which can be use in a project ??

Thanks for all your help

Right click your project in the package explorer and locate your CSS file. It should show up automatically if your source path is set up correctly and the asset is descendant of that directory. Then just make sure the checkbox next to the CSS file name is checked.
