title: CMake does not produce .exe file
body: <p>I have built a CERN's ROOT script which based on c++ and i write(edit an example) CMakeList.txt. I am so rokie at CMake btw. 
  When I command to compile with <code>cmake ..</code>, it done correctly -i think- with no errors. But .exe file what i want to produce does not appear. 
  My directory orders </p>
  
  <pre><code>/Project
  ../TLV.cpp  
  ../CMakeLists.txt
  ../build
  </code></pre>
  
  <p>There is my CMakeLists.txt </p>
  
  <pre><code>cmake_minimum_required(VERSION 2.8)
  project(TLV)
  #Set CXX flags to compile with c++11 and error warnings quiet
  set(CMAKE_CXX_FLAGS "-O3 -fPIC -Wall -Wextra -std=c++11 -m64")

  <p>I do not get it where I am wrong.</p>
