configure & build system
|
|
------------------------
|
|
|
|
- The -process/-fully-process/-dont-process configure options have been
|
|
removed due to being unnecessary and counterproductive.

|
|
_after_ building Qt in case you want to use Visual Studio to work on Qt.
|
|
- [QTBUG-37961] Qt plugins contain version info again.
|

|
|
from a pre-existing Qt installation.
|
|

|
|
|
|
