Problem- can't build after exporting OS program to Eclipse IDE

I exported the blinky example via CLI and i’m trying to build it through Eclipse IDE.
I followed the tutorial from here:

when I try to build I recieve this error log:

2:20:28 **** Incremental Build of configuration Default for project mbed-os-example-blinky ***
make all 
Compile: main.cpp
arm-none-eabi-g++.exe: error: /.../mbed-os-example-blinky/mbed-os-example-blinky/mbed-os: No such file or directory
make[1]: *** [/.../mbed-os-example-blinky/mbed-os-example-blinky/Makefile:1787: main.o] Error 1
make: *** [Makefile:26: all] Error 2
"make all" terminated with exit code 2. Build might be incomplete.

12:20:29 Build Failed. 2 errors, 0 warnings. (took 1s.353ms)

It looks like the path for this file: arm-none-eabi-g++.exe is the OS path instead of the eclipse path which I updated at project->properties ->C/C++ Build->Environment.

How to fix this?
Thank you.
