But since f31b6244950 (Merge branch 'yw/cmake-updates', 2022-06-07) and with the preceding commits cmake and ctest are not Windows-specific anymore. So let's set those same options by default on Windows, but do so with the set() facility. As noted in cmake's documentation[1] this integrates nicely with e.g. cmake-gui. On *nix we don't set any custom options. The change in 2ea1d8b5563 didn't discuss why Windows should have divergent defaults with "cmake" and "make", but such reasons presumably don't apply on *nix. I for one am happy with the same defaults as the tests have when running via the Makefile. With the "message()" addition we'll emit this when running cmake: Generating hook-list.h -- Using user-selected test options: -vixd -- Configuring done -- Generating done -- Build files have been written to: /home/avar/g/git/contrib/buildsystems/out Unfortunately cmake doesn't support a non-hacky way to pass variables to ctest without re-running cmake itself, so when re-running tests via cmake and wanting to change the test defaults we'll need: GIT_TEST_OPTS=-i cmake -S contrib/buildsystems -B contrib/buildsystems/out && ctest --jobs=$(nproc) --test-dir contrib/buildsystems/out -R t0071 --verbose 1. https://cmake.org/cmake/help/latest/command/set.html#set-cache-entry Signed-off-by: Ævar Arnfjörð Bjarmason --- contrib/buildsystems/CMakeLists.txt | 46 +++++++++++++++++++++++++++-- 1 file changed, 44 insertions(+), 2 deletions(-) diff --git a/contrib/buildsystems/CMakeLists.txt b/contrib/buildsystems/CMakeLists.txt index f0de37b35a1..6a3240d4ffa 100644 --- a/contrib/buildsystems/CMakeLists.txt +++ b/contrib/buildsystems/CMakeLists.txt @@ -49,7 +49,7 @@ To use this in Visual Studio: Open the worktree as a folder.
