Check what the https://gdal.org/programs/gdalbuildvrt.html does: https://github.com/OSGeo/gdal/blob/master/apps/gdalbuildvrt_bin.cpp#L192-L196 which is this call https://github.com/OSGeo/gdal/blob/master/apps/gdalbuildvrt_lib.cpp#L1691 which uses this builder class https://github.com/OSGeo/gdal/blob/master/apps/gdalbuildvrt_lib.cpp#L1769 which is/can be built as a library and linked against.
