[PATCH v3 0/7] CMake(Visual C) support for js/doc-unit-tests

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

The recent patch series that adds proper unit testing to Git requires a
couple of add-on patches to make it work with the CMake build on Windows
(Visual C). This patch series aims to provide that support.

This patch series is based on js/doc-unit-tests.

Changes since v2:

 * Thanks to Phillip Wood's prodding, I managed to avoid the "Empty
   Namespace" problem in Visual Studio's Test Explorer.

Changes since v1:

 * The code added to test-lib.c now avoids using a strbuf.
 * The unit tests are now also handled via CTest.
 * While at it, I cleaned up a little in the CTest-related definitions.

Johannes Schindelin (7):
  cmake: also build unit tests
  unit-tests: do not mistake `.pdb` files for being executable
  unit-tests: do show relative file paths
  artifacts-tar: when including `.dll` files, don't forget the
    unit-tests
  cmake: fix typo in variable name
  cmake: use test names instead of full paths
  cmake: handle also unit tests
