In CLion, header only library: file “does not belong to any project target, code insight features might not work properly”

Question

I have a header-only library project set up with the cmake command:

add_library(my_library INTERFACE)

and I also added

target_         


        

Answer 1

You can add the header files to your project like this:

set(SOURCE_FILES main.cpp MyClass1.cpp MyClass1.h MyClass2.cpp MyClass2.h)

You can also set it in multiple steps like so:

set(SOURCE_FILES main.cpp)
set(SOURCE_FILES ${SOURCE_FILES} MyClass1.cpp MyClass1.h)
set(SOURCE_FILES ${SOURCE_FILES} MyClass2.cpp MyClass2.h)

Though as mentioned in the comments, you probably shouldn't be adding the header files to your project at all.
