CMAKE creates a static executable instead of using a dynamic library

My cmake file

cmake_minimum_required(VERSION 2.8.4)
project(libtry CXX)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(EXE_NAME libtry)

file(GLOB_RECURSE MAIN_SRC_FILES "src/*.cpp")
add_library (Try SHARED ${MAIN_SRC_FILES})


set(SOURCE_FILES main.cpp)
add_executable(${EXE_NAME} ${SOURCE_FILES})
target_link_libraries(${EXE_NAME} Try)

      

        
        
        
      

    

This file works and creates two files: a .so file and an executable and it works fine. The problem even after deleting the .so file, the executable works fine, which means the executable is statically linked.

Why is this happening and why isn't cmake using the .so file dynamically?
