I’m trying to create an If statement in c++ that will act based on the GL_RENDERER.

In engine.cpp Im trying
Shown here

void operator()(osg::GraphicsContext* graphicsContext) override
        {
            Log(Debug::Info) << "OpenGL Vendor: " << glGetString(GL_VENDOR);
            Log(Debug::Info) << "OpenGL Renderer: " << glGetString(GL_RENDERER);
            Log(Debug::Info) << "OpenGL Version: " << glGetString(GL_VERSION);
            glGetIntegerv(GL_MAX_TEXTURE_IMAGE_UNITS, &mMaxTextureImageUnits);
            glGetString(GL_RENDERER, &mRenderer);
        }

        int getMaxTextureImageUnits() const
        {
            if (mMaxTextureImageUnits == 0)
                throw std::logic_error("mMaxTextureImageUnits is not initialized");
            return mMaxTextureImageUnits;
        }

    private:
        int mMaxTextureImageUnits = 0;
        std::string mRenderer = "";
    };

then in postprocesser.cpp
Shown here

if (reinterpret_cast<const char*>(GL_RENDERER_INFO) == "GL4ES wrapper") {
            mCanvases[frameId]->setTextureDepth(getTexture(Tex_Depth, frameId));
        } else {
            mCanvases[frameId]->setTextureDepth(getTexture(Tex_OpaqueDepth, frameId));
        }       
        
        mCanvases[frameId]->setTextureDistortion(getTexture(Tex_Distortion, frameId));

what am I missing here…
