title: What is the default search path for find_package in windows using cmake?
body: <p>I am porting some code over to windows and my cmake checks for the package Libavahi using</p>
  
  <pre><code>find_package(Libavahi)
  </code></pre>
  
  <p>I have the headers, dll, etc. but I'm not sure where to place these such that cmake will find them.</p>
  
  <p>Where can I put these files to be found by cmake?  They're in a folder called <code>usr</code>.</p>
  
  <p>I see that the module path is specified using:</p>
  
  <pre><code>set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/")
  </code></pre>
  
  <p>but I'm wondering if there is a default location that will be searched as well</p>
