Build error on CentOS 7.5

Hi,

I'm using a CentOS 7.5 (3.10.0-693.2.2.el7.x86_64) docker instance to build ocio with devtoolset-6 and my build fails with the following error:

/oss/imageworks/OpenColorIO/src/apps/ocioconvert/main.cpp: In function 'int main(int, const char**)':
/oss/imageworks/OpenColorIO/src/apps/ocioconvert/main.cpp:122:66: error: cannot convert 'OpenImageIO_v1_9::ImageInput::unique_ptr {aka std::unique_ptr<OpenImageIO_v1_9::ImageInput>}' to 'OpenImageIO_v1_9::ImageInput*' in initialization
         OIIO::ImageInput* f = OIIO::ImageInput::create(inputimage);
                                                                  ^
/oss/imageworks/OpenColorIO/src/apps/ocioconvert/main.cpp:311:69: error: cannot convert 'OpenImageIO_v1_9::ImageOutput::unique_ptr {aka std::unique_ptr<OpenImageIO_v1_9::ImageOutput>}' to 'OpenImageIO_v1_9::ImageOutput*' in initialization
         OIIO::ImageOutput* f = OIIO::ImageOutput::create(outputimage);

I also get these warnings initially during the build but not sure if they eventually cause the build to error out?

/oss/imageworks/OpenColorIO/build/ext/yaml-cpp/src/ptr_stack.h:35:8: warning: 'template<class> class std::auto_ptr' is deprecated [-Wdeprecated-declarations]
   std::auto_ptr<T> t(m_data.back());

I'm following the build instructions on this page. I have already built oiio and its installed in the default system location and ocio is picking that up correctly during the build process. But I came across this post re the cyclic dependency issue between ocio and oiio and I'm wondering if I need to follow the instructions on that thread in Linux as well since I intend to build all the ocio apps?

Thanks,
Sachin
