Well,I am new to CMake and want to edit flight simulation code in eclipse instead of visual studio. For that purpose, I downloaded the source code of Simgear, CMake, Boost libraries, open scene graph and openalsoft.

Now I have all the data available but I dont know where to place some of these libraries. As a result, when I run CMake and give reference to my flightgear code, it complains that the openscenegraph libraries are not installed.

Please help me with where I need to put all these files so as to convert my code to eclipse using CMake. I have already installed boost and openal libraries. Only issue is of openscenegraph libraries which I put in program files at the following path "C:\Program Files\OpenSceneGraph-3.4.0" but CMake can't access it. The error code is

  • What **approach** do you use for find OpenAL library [in that question](http://stackoverflow.com/questions/40373379/compilation-of-flightgear-code-in-eclipse-using-cmake)? Have you tried (and how) this approach for OSG library? There are many libraries used for development under CMake, and having distinct questions for **every** library ... it is not a purpose of Stack Overflow. – Tsyvarev Nov 07 '16 at 09:29
  • I entered a code snippet in the Findopenal.cmake to address to the location of my libraries and that did work. I tried to do the same for findopenscenegraph.cmake but it gave errors as ......Could not find a package configuration file provided by "C:/Program Files/OpenSceneGraph-3.4.0/build" with any of the following names: C:/Program Files/OpenSceneGraph-3.4.0/buildConfig.cmake c:/program files/openscenegraph-3.4.0/build-config.cmake – MSM Nov 07 '16 at 10:21
  • @wasthishelpful yes it is the same question but there were no more any comments comming so thought that the question may be outdated so i posted a new one.. I'll be very grateful If you please tell me how to configure this openscenegrah. – MSM Nov 07 '16 at 10:27
  • `Only issue is of openscenegraph libraries which I put in program files at the following path "C:\Program Files\OpenSceneGraph-3.4.0"` - Do you **manually** copy some files (which ones?) into given directory? This is not an usual way for installing things. Why do not follow official guide for install OSC, e.g. [this one](https://github.com/openscenegraph/OpenSceneGraph/blob/master/README.md)? **Modification** of `FindXXX.cmake`, as you did for find `OpenAL` library, is also uncommon: instead, you need to set environment/CMake variables for hint library location. – Tsyvarev Nov 07 '16 at 10:43

I'm not a CMake expert, here some things I did in order to create ROS & OSG project in Linux:

add an environment variable (if it is not there yet) to the .bashrc file:

export PATH=${PATH}: .../OpenSceneGraph-3.4.0/bin (your absolute path)

then in CMake file add:

FIND_PACKAGE ( OpenSceneGraph COMPONENTS osgSim osgUtil osgDB osgFX osgGA osgTerrain osgViewer osgText osgWidget osgManipulator osg osgShadow)

target_link_libraries(name_of_your_executable ${PROJECT_NAME} ${OPENSCENEGRAPH_LIBRARIES})

For more information check CMake documentation here and here
