title: CMake can't find GLEW
body: <p>I've read this [1], but in my case CMake says it can't find glew.</p>
  
  <p>I'm on Windows and there is a FindGLEW.cmake file in my CMake modules folder, presumably put there when I installed CMake-3.6.  I found GLEW on sourceforge and downloaded the zip file for Windows.  I unzipped and installed in C:\Program Files\glew.  When I've created my own libraries and used CMake to build and install them, this is the default location they are installed to so I am pretty confident I'm OK here.</p>
  
  <p>The snippet from my CMakeLists.txt is:</p>
  
  <pre><code>find_package(GLEW REQUIRED)
  include_directories(${GLEW_INCLUDE_DIRS})
  link_libraries(${GLEW_LIBRARIES})
  </code></pre>
  
  <p>The actual error message from CMake is:</p>
  
  <pre><code>CMake Error at C:/Program Files/CMake/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
    Could NOT find GLEW (missing: GLEW_INCLUDE_DIR GLEW_LIBRARY)
  Call Stack (most recent call first):
    C:/Program Files/CMake/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
    C:/Program Files/CMake/share/cmake-3.6/Modules/FindGLEW.cmake:44 (find_package_handle_standard_args)
    source/CMakeLists.txt:5 (find_package)
  </code></pre>
  
  <p>Is it possible the FindGLEW.cmake is broken?  I've looked at a couple of other FindXXXXX.cmake files and they are like snowflakes, each one pretty unique.  So it's hard for me to say with any certainty that it's following convention.</p>
