Dear Aashish:
        What's MIDAS support?   I just have tried modify the two variables VES_USE_CURL and VES_USE_LIBARCHIVE in the ves-superbuild.cmake file ON. But I can't compile the VES successfully.
        Some days ago  I use the command 'git clone http://XXXXXXX(download url)' download the ves. It uses the OpenGL ES 2.0. And Its LICENSE version is also 2.0 too. I think it may be the most latest version.
        My Xcode version is 4.6.2. The MacOS version is 10.8.5.
       
       Before I  build the example named Kiwiviewer in the dir named iOS  I just use these commands to compile the frameworks.commands like this:
                mkdir <build dir>
                cd <build dir>
                cmake -DVES_IOS_SUPERBUILD=1 <ves src dir>
                make -j4
        Then I config the build phases in the project target. Of course I download the DropboxSDK.framework and pcl.framework from the internet.    And all files in the dir frameworks are not red. It means I successfully import the frameworks.But I meet these link Errors like last E-mail. 
        I am really bored by it. So please help me~   THANK YOU VERY VERY MUCH!

Are you trying to build VES with MIDAS support intentionally? Also can you tell us the VERSION of VES you are tying to use? 


Thanks
