[PATCH 0/5] Some fixes and an improvement for using CTest on Windows

As part of the CMake definition, Git enjoy support for running the test suite via CTest.

In https://github.com/git-for-windows/git/issues/3966, it has been reported that this does not work out of the box, though, but causes a couple of test failures instead. These problems are not caught by Git's CI runs because the vs-tests jobs actually use prove to run the test suite, not CTest.

In addition to fixing these problems, this patch series also addresses a
long-standing gripe I have with the way Git's CMake definition supports
CTest: It edits t/test-lib.sh, which leaves this file eternally modified
(but these modification should never be committed, they refer to a
local-only, configuration-dependent directory).

Johannes Schindelin (5):
  cmake: align CTest definition with Git's CI runs
  cmake: copy the merge tools for testing
  tests: explicitly skip `chmod` calls on Windows
  add -p: avoid ambiguous signed/unsigned comparison
  cmake: avoid editing t/test-lib.sh
