Help: problem with unresolved inclusions: "pico/stdlib" i add this to my "path and symbols" but i still have errors

[oDeenBrowno]

Hi I am trying to import C++ projects into Eclipse.

I open my project using the wizard "create a makefile from existing code"

I right click on the project name, and under "paths and symbols" i add
C:\Program Files\Raspberry Pi\Pico SDK v1.5.0\pico-sdk\src\common\pico_stdlib\include
this contains a pico_stdlib.h file which has several include files
>all the include in the pico_stdlib files say unresolved

What am i doing wrong?
