Read AutoCAD's DWG file format

Hello LibreCAD developers：
  I compiled LibreCAD according to the official documentation and can build it with QT, but I found that it seems to be not so friendly to AutoCAD DWG files. Even DXF files drawn in AutoCAD, I opened them with LibreCAD, and the text in the files was gone. What plugins can I use to improve these features?

Dwg support is minimum. Dxf support is only up to dxf 2007.

Can I use LibreDWG, the open source DWG file library, to complete LibreCAD's DWG format

I think it's possible, if you want join the development.

Sadly it is still not possible for LibreCAD 2.*!
It was extensively discussed back in 2012 iirc that the LibreDWG license is not compatible with GPLv2, to which LibreCAD is still bound because of its QCAD roots.

If libredwg would be used as external library that is linked against, adding a linking exception for libredwg to the librecad copyright license terms should resolve that GPv2/GPLv3 issue https://www.gnu.org/licenses/gpl-faq.html#GPLIncompatibleLibs. There should already be such an exception there for Qt, since it is dual licensed under QT commercial license and GPLv3+ afaik, neither of which are compatible with GPLv2
