Ninja is used as a default generator

[OleksandrKvl]

Brief Issue Summary

After recent VSCode update to 1.68.0 and CMake tools extension to v1.11.25 my configuration step stopped working. The problem is that now it passes -G Ninja option even though cmake.generator option is empty.

Today I faced the same problem.

[DrMagicalStone]

One solution is to make cmake.generator not empty, such as "cmake.generator": "Unix Makefiles". To set an exist generator.

[FredM67]

Same problem !!!!
What making such breaking changes ?!?! it just makes dev lose their time to first understand what's going on and then repair !!!!

[FredM67]

Please revert to the (previous) default behavior

[Lyvsain]

Same here ! My whole team got errors since this morning...

[Flame12220]

Got exactly the same issue here too. Didnt know where the issue came from but after i installed the CMake Tool v1.10.5 everything went back to normal.

[Andrew9317]

Yup same issue here.

We're sorry for the disruption. We will investigate and get a fix out as soon as possible.

We've identified the root cause. It was this PR: #2502
We're working on a fix.
