From ee9e66e4e762075f882ec18ed51270099723cfc9 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 18 Oct 2022 10:59:04 +0000 Subject: cmake: avoid editing t/test-lib.sh In 7f5397a07c6c (cmake: support for testing git when building out of the source tree, 2020-06-26), we implemented support for running Git's test scripts even after building Git in a different directory than the source directory. The way we did this was to edit the file `t/test-lib.sh` to override `GIT_BUILD_DIR` to point somewhere else than the parent of the `t/` directory. This is unideal because it always leaves a tracked file marked as modified, and it is all too easy to commit that change by mistake. Let's change the strategy by teaching `t/test-lib.sh` to detect the presence of a file called `GIT-BUILD-DIR` in the source directory. If it exists, the contents are interpreted as the location to the _actual_ build directory. We then write this file as part of the CTest definition. To support building Git via a regular `make` invocation after building it using CMake, we ensure that the `GIT-BUILD-DIR` file is deleted (for convenience, this is done as part of the Makefile rule that is already run with every `make` invocation to ensure that `GIT-BUILD-OPTIONS` is up to date).
