| <p>Find OpenSceneGraph</p> |
| <p>This module searches for the OpenSceneGraph core “osg” library as well |
| as OpenThreads, and whatever additional COMPONENTS (nodekits) that you |
| specify.</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">See</span> <span class="n">http</span><span class="p">:</span><span class="o">//</span><span class="n">www</span><span class="o">.</span><span class="n">openscenegraph</span><span class="o">.</span><span class="n">org</span> |
| </pre></div> |
| </div> |
| <p>NOTE: To use this module effectively you must either require CMake >= |
| 2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place |
| FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and |
| Find<etc>.cmake files into your CMAKE_MODULE_PATH.</p> |
| <hr class="docutils" /> |
| <p>This module accepts the following variables (note mixed case)</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">OpenSceneGraph_DEBUG</span> <span class="o">-</span> <span class="n">Enable</span> <span class="n">debugging</span> <span class="n">output</span> |
| </pre></div> |

| <span class="n">automatically</span> |
| </pre></div> |
| </div> |
| <p>The following environment variables are also respected for finding the |
| OSG and it’s various components. CMAKE_PREFIX_PATH can also be used |
| for this (see find_library() CMake documentation).</p> |
| <dl class="docutils"> |
| <dt><code class="docutils literal"><span class="pre"><MODULE>_DIR</span></code></dt> |
| <dd>(where MODULE is of the form “OSGVOLUME” and there is a FindosgVolume.cmake file)</dd> |
| <dt><code class="docutils literal"><span class="pre">OSG_DIR</span></code></dt> |
| <dd></dd> |
| <dt><code class="docutils literal"><span class="pre">OSGDIR</span></code></dt> |
| <dd></dd> |
| <dt><code class="docutils literal"><span class="pre">OSG_ROOT</span></code></dt> |
| <dd></dd> |
| </dl> |
| <p>[CMake 2.8.10]: The CMake variable OSG_DIR can now be used as well to |
| influence detection, instead of needing to specify an environment |
| variable.</p> |
| <p>This module defines the following output variables:</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span>OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found? |
| </pre></div> |
