Description
Hi, @madler
The CMake build would rename zconf.h to zconf.h.included.
$ git status
On branch master
Your branch is up to date with 'origin/master'.
Changes not staged for commit:
(use "git add/rm <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
deleted: zconf.h
Untracked files:
(use "git add <file>..." to include in what will be committed)
build/
zconf.h.included
Mostly this would not be a quesion. But sometimes, some build rules or system would require that source file should not be changed after the build.
The git blame shows that the rename part zconf.h in CMakeLists.txt is changed 10 years ago. Perhaps this part can be optimized.

75 message(STATUS "to 'zconf.h.included' because this file is included with zlib")
