title: Change default CMakeLists.txt in CLion to include warnings
body: <p>In CLion the default CMakeLists.txt sets the C++11 compiler flag only. I'd like to have warnings and the pedantic flag by default in all my projects.</p>
  
  <p>This is by default</p>
  
  <pre><code>set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
  </code></pre>
  
  <p>and I'd like to have this by default so I don't have to change it every time I create a new project</p>
  
  <pre><code>set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -W -Wall -Wextra -pedantic")
  </code></pre>
  
  <p>In the "Settings" - "File and Code Templates" I can change the C++ header/source template but not the CMakeLists.txt template. Is there any way I can change the default CMakeLists.txt template in CLion?</p>
