[Bug] cmaketools tirelessly cleans before building

[YexuanXiao]

Brief Issue Summary

I use SSH to remotely build on the server, but even though I set "cmake.clearOutputBeforeBuild": false in the local user settings, workspace settings, and remote server settings, cmaketools still cleans before building, causing the build cache to be completely ineffective.

Hi @YexuanXiao, thanks for reporting here!

Verified this issue on CMake Tools v1.20.53 and v1.21.17(pre-release), when I use SSH to remotely build, and set "cmake.clearOutputBeforeBuild": false in workspace settings, cmake tools will not clean before building.
Details please see following video:

@YexuanXiao The cmake.clearOutputBeforeBuild setting does not change any behavior regarding a build clean, it is specific to whether the output window will be cleared.

Did you enable "cmake.buildTask"? I met the same problem you mentioned, when "cmake.buildTask" is enabled.

It is enabled by default. After turning it off, everything is fine, thanks. @gcampbell-msft is this intentional?

@ElemenTP @YexuanXiao Thanks for the additional context! It sounds like there may be a bug when the cmake.buildTask is enabled.

We will investigate this as soon as we can based on bandwidth. However, to answer your question, no, based on the definition in the package.json https://github.com/microsoft/vscode-cmake-tools/blob/75182235a5734dc0a00ffef8e6cbd295d85e0cff/package.json#L2706C9-L2711C11, cmake.buildTask is defaulted to false.
