title: cmake if else with option
body: <p>I have a problem using <code>option</code> together with <code>if-else</code> statement in cmake.</p>
  <pre><code>project(test)
  
  option(TESTE &quot;isso é um teste&quot; OFF)
  
  if(TESTE)
    message(&quot;true&quot;)
  else()
    message(&quot;false&quot;)
  endif()
  
  add_executable(test main.cpp)
  </code></pre>
  <p>It always displays <code>true</code> even if I put OFF in the options, what am I doing wrong?</p>
