How to link static libraries in cmake

Question

I am trying to link GLFW in my project. There is screenshot of my project structure:

This is my CMakeLists.txt:

cmake_minimum_required(VERSION 3.15)
project(testo)

set(CMAKE_CXX_STANDARD 17)

add_executable(testo main.cpp)
add_library(glfw3 STATIC main.cpp)

include_directories(lib/glfw/include/)

find_library(GLFW glfw3 lib/glfw/lib)
target_link_libraries(testo LINK_PUBLIC ${GLFW})

Howewer, when i try to run project in clion, it gives me error:

====================[ Build | testo | Debug ]===================================
"C:\Program Files\JetBrains\CLion 2019.2.5\bin\cmake\win\bin\cmake.exe" --build C:\Users\Student\testo\cmake-build-debug --target testo -- -j 2

Here is some github example.
Here is some SO question you are duplicating.

Based on that this should look like this:

cmake_minimum_required(VERSION 3.15)
project(testo)

set(CMAKE_CXX_STANDARD 17)

find_package(GLEW REQUIRED)

add_executable(testo main.cpp)
target_link_libraries(testo PUBLIC ${GLEW_LIBRARIES})
target_include_directories(testo PUBLIC ${GLEW_INCLUDE_DIRS})
