FetchContent: Add variable to customise base source dir (!7953) · Merge requests · CMake / CMake

Chris Wright requested to merge inkychris/cmake:20536-fetchcontent-base-source-dir into master Nov 24, 2022

Adds FETCHCONTENT_BASE_SOURCE_DIR to allow users to specify where FetchContent downloads content, without modifying paths for the build/subbuild paths. This allows multiple build directories to share downloaded content.

Closes #20536
