Adding CDT Nature and Managed Build to an existing project requires using of not public API-s of CDT

The following packages need to be imported:
org.eclipse.cdt.managedbuilder.internal.core.Configuration
org.eclipse.cdt.managedbuilder.internal.core.ManagedProject

The following quotation explains modetails:

If you have an existing project type and want to add CDT capabilities & features to it, you can try the code below in your plug-in:

CProjectNature.addCNature(fProject, mon);
ICProjectDescriptionManager mgr = CoreModel.getDefault().getProjectDescriptionManager();
ICProjectDescription des = mgr.getProjectDescription(fProject, true);

if (des != null)
        return; // C project description already exists

des = mgr.createProjectDescription(fProject, true);

ManagedBuildInfo info = ManagedBuildManager.createBuildInfo(fProject);
IProjectType projType =
         ManagedBuildManager.getExtensionProjectType("my.project.type"); // or get projectType from UI
IToolChain toolChain =
         ManagedBuildManager.getExtensionToolChain("my.toolchain"); // or get toolChain from UI

ManagedProject mProj = new ManagedProject(fProject, projType);
info.setManagedProject(mProj);

IConfiguration[] configs = ManagedBuildManager.getExtensionConfigurations(toolChain, projType);

for (IConfiguration icf : configs) {
    if (!(icf instanceof Configuration)) {
        continue;
    }
    Configuration cf = (Configuration) icf;

    String id = ManagedBuildManager.calculateChildId(cf.getId(), null);
    Configuration config = new Configuration(mProj, cf, id, false, true);

    ICConfigurationDescription cfgDes =
    des.createConfiguration(ManagedBuildManager.CFG_DATA_PROVIDER_ID,
                                         config.getConfigurationData());
    config.setConfigurationDescription(cfgDes);
    config.exportArtifactInfo();

    IBuilder bld = config.getEditableBuilder();
    if (bld != null) { bld.setManagedBuildOn(true); }

    config.setName(toolChain.getName());
    config.setArtifactName(fProject.getName());

}

mgr.setProjectDescription(fProject, des);

Of course, you have to replace "my.project.type" and "my.toolchain" with the appropriate CDT project type and toolchains, respectively.

There's still one caveat, though. You will notice the code directly instantiates an instance of Configuration which is inside an internal package of CDT. Unfortunately, as of now there's no "valid" way to create it with the same parameters as we did. We will have to request an addition to the API to support this.
