C++ Compile can’t find #include files

I want to add a Groom Component for my character’s hair. However, when I try to include “GroomComponent.h” to my .cpp file, I get an error.
Note: I tried right clicking the .uproject file and creating project file)

You must add HairStrandsCore to your module dependencies in PROJECTNAME.build.cs

As it specified in the documentation
