This patch allows all the sqldrivers to be built as a standalone project. It is not possible to build each plugin separately due to the configuration features definition being located in the sqldriver's folder CMakeLists.txt. In other words, the project needs to be generated from the src/plugins/sqldrivers/CMakeLists.txt file. Fixes: QTBUG-82962 Change-Id: If41c7e3827589391830a894a9c998d2e56239562 Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>
