Walkthrough

The freetype dependency build definition is updated to apply a new patch (cmake_minimum.patch) during the preprocess stage. The patch file raises the cmake_minimum_required version in FreeType's CMakeLists.txt from 2.8.12 to 3.12. In freetype.mk, the patch is added to the $(package)_patches list and a new $(package)_preprocess_cmds macro is introduced to invoke patch -p1 with the patch file before the configure/build steps.

Code Review

Faithful, minimal backport of bitcoin#32693 that fixes freetype's depends build under CMake 4 by patching freetype's CMakeLists.txt to require CMake >= 3.12. The freetype.mk wiring (patch registration + preprocess_cmds) matches established depends conventions, no Dash-specific interactions, and no prerequisite gaps.

Note: posted as a COMMENT review because GitHub rejected the clean APPROVE review for this stale, no-longer-head commit.

Code Review

Faithful, minimal backport of bitcoin#32693 that fixes freetype's depends build under CMake 4.x by adding a patch raising freetype's cmake_minimum_required from 2.8.12 to 3.12 and wiring it through freetype.mk via the standard $(package)_patches / $(package)_preprocess_cmds pattern. The patch contents and depends glue match upstream exactly, the depends infrastructure used is already established in Dash's tree, and no prerequisite Bitcoin Core PRs are required. Commit history is clean (upstream-authored content commit + merge commit with full PR description and Tree-SHA512 trailer), and there are no prior findings to carry forward from the previous review at e0d2946c (delta is empty).
