eclipse c++ add a lib ? how do I ?

[highspider]

how do add libs to the complier for eclipse?
and what is process correctly called because I have NO luck searching it.

if I was using the command line it would just be adding -lncurese

g++ GAME.cpp -o game -lncurses

found it finally

right click the project file -> select properties
settings->GCC C++ Linker->libraries->add new
ncurses

which is now the same as -lncures
i guess the -l stands for library
