Build with eclipse

[MrHause]

Hi,
I know that it is not an issue, but I'm new and have know idea where to look for a help. So previously I used ESPRESSIF RTOS SDK and there after few steps I was able to build project in eclipse. After setting project's properties I had to call "make menuconfig" in the project folder which include makefile. Then it was possible to build project in eclipse without errors. Is it possible to import folder including makefile from some of the given example and make it build in eclipse?
I don't have to even built it in eclipse, but how to make project to see all of libraries to let me work with the code? Do I have to add some environment variable? It's compiling but can solve includes or even simple declaration like uint8_t. I import project as cross gcc and do some setups like in espressif tutorial.
