cmake: Shouldn't use sourcedir for building
Metadata
Current evaluation
Request for cmake plugin to use out-of-source builds (build in SNAPCRAFT_PART_BUILD instead of SNAPCRAFT_PART_SRC). 2689 days old, no labels, no comments, no maintainer interaction. The current craft-parts cmake plugin already implements out-of-source builds via get_out_of_source_build() returning True.
Suggested action: close stale
Reason: The issue is 7+ years old with zero maintainer interaction and references the legacy snapcraft/plugins/cmake.py which no longer exists. The requested behavior is now implemented: the current craft-parts CMakePlugin explicitly declares get_out_of_source_build() -> True, meaning cmake configures against the source but builds in the build directory, which is exactly what the reporter asked for.

Issue body
Currently cmake plugin runs configuration using the files in SNAPCRAFT_PART_SRC, IMO it should copy them to SNAPCRAFT_PART_BUILD and run against it so that one can patch these files in the build step (before running `snapcraftctl build`).
