to the best of my knowledge there is two solutions.
1- you can create an eclipse headless plug-in and then run eclipse from the command line. Notice that when running eclipse from the command line you still needs to open an workspace and create a C project and link its source folder with the SRC code location. If you wish I can provide you with an example.
2- you can run CDT outside eclipse. To do that you needs those jar files (any version is ok):
org.eclipse.cdt.core_5.9.1.201502131403.jar
org.eclipse.cdt.ui_5.9.0.201502131403.jar
org.eclipse.core.contenttype_3.4.200.v20140207-1251.jar
org.eclipse.core.jobs_3.6.1.v20141014-1248.jar
org.eclipse.core.resources_3.9.1.v20140825-1431.jar
org.eclipse.core.runtime_3.10.0.v20140318-2214.jar
org.eclipse.equinox.common_3.6.200.v20130402-1505.jar
org.eclipse.equinox.preferences_3.5.200.v20140224-1527.jar
org.eclipse.osgi_3.10.2.v20150203-1939.jar
but in this case you have to manage the included files manually. An example:

You have to do something like this. but c project instead of java project. Also info about headless eclipse plugins you can find with a google search.
public class ConsoleApp implements IApplication {
@Override
public Object start(IApplicationContext context) {
try {
String[] args = (String[]) context.getArguments().get(
"application.args");
Platform.getBundle("AnyBundleYouNeedsToStart").start();
} catch (Exception e) {
e.printStackTrace();
}
importSourceCode("path to source");
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IProject project = root.getProject("Temp Project");
try {
project.delete(true, null);
} catch (CoreException e1) {
}
return IApplication.EXIT_OK;
}
@Override
public void stop() {
}
private static String importSourceCode(String absolutePathToDocument) {
IProject project = null;
String srcFolderLocationInTheProject = "src";
String projectName = "Temp Project";
try {
// Create a project
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
project = root.getProject(projectName);
if (project.exists()){
project.delete(true, null);
}
project.create(null);
project.open(null);
// Because we need a java project, we have to set the Java nature to
// the created project
IProjectDescription description = project.getDescription();
description.setNatureIds(new String[] { JavaCore.NATURE_ID });
project.setDescription(description, null);
// create Java project
IJavaProject javaProject = JavaCore.create(project);
// Set the Java build path
IFolder binFolder = project.getFolder("bin");
binFolder.create(false, true, null);
javaProject.setOutputLocation(binFolder.getFullPath(), null);
// Link source folder
ArrayList<IClasspathEntry> entries = new ArrayList<IClasspathEntry>(
Arrays.asList(javaProject.getRawClasspath()));
// remove all other source entries, because the main project folder
// is a source entry and we can't save other source entry nested in
// it
for (int i = 0; i < entries.size(); i++) {
if (entries.get(i).getEntryKind() == IClasspathEntry.CPE_SOURCE) {
entries.remove(i);
}
}
IPath srcPath = javaProject.getPath().append(
srcFolderLocationInTheProject);
IClasspathEntry srcEntry = JavaCore.newSourceEntry(srcPath, null);
entries.add(srcEntry);
javaProject.setRawClasspath((IClasspathEntry[]) entries
.toArray(new IClasspathEntry[entries.size()]), null);
//link the folder with the resources
IFolder srcFolder = project.getFolder(srcFolderLocationInTheProject);
srcFolder.createLink(new Path(absolutePathToDocument.replaceFirst("file:/", "")), IFolder.FOLDER, null);
return "file:/"
+ ResourcesPlugin.getWorkspace().getRoot().getLocation()
+ "/" + projectName + "/" + srcFolderLocationInTheProject;
} catch (Exception e) {
e.printStackTrace();
try {
project.delete(true, null);
} catch (CoreException e1) {
e1.printStackTrace();
}
return null;
}
}
}
