You need to check your project's includes because the problem is that it is not finding the linker-script-debug.ld file.
You can see the project includes by right-clicking on the project, then Properties>C/C++ Build>Settings.
Where did you get this project? it has a weird folder name with a dot in it (Blinking_LED_copy_mcuxpresso_k64f.zip_expanded). Maybe that is causing problems. I have never worked directly on a folder with a dot in the name but maybe windows is having a hard time using that.
I would recommend to remove the project from mcuxpresso, rename the folder to just Blinking_LED_copy_mcuxpresso_k64f, and import the project again. Then check the includes to see if the builder is referencing the correct paths.
