From 5d0fb490a9e0378cb132777a554ccb519f33f652 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 13 Sep 2024 18:33:28 +0200 Subject: [PATCH] cmake: generalize the handling of the `UNIT_TEST_OBJS` list In a15d4465a991 (cmake: also build unit tests, 2023-09-25), I accommodated the CMake definition. Seeing that a `UNIT_TEST_OBJS` list was introduced that was built by transforming the `UNIT_TEST_PROGRAMS` list and then adding a single, hard-coded file ("t/unit-tests/test-lib.c"), I decided to hard-code that in the CMake definition, too. The reason why I hard-coded it instead of imitating the `parse_makefile_for_sources()` paradigm that was used elsewhere when using the `Makefile` as source of truth for given lists of files: This function expects _only_ hard-coded values, and that transformed `UNIT_TEST_PROGRAMS` list complicated everything. In 872721538c26 (cmake: fix build of `t-oidtree`, 2024-07-12), I accommodated the CMake definition again, after seeing that the `UNIT_TEST_OBJS` was still defined via that transformed list but now appending _two_ hard-coded files ("t/unit-tests/lib-oid.c" joined the fray). In e7e6d74d2b71 (Makefile: stop listing test library objects twice, 2024-09-09), the `Makefile` was changed so that `UNIT_TEST_OBJS` is finally only constructed using hard-coded file names just like the other `*_OBJS` variables. I missed that and therefore did not adjust the CMake definition. Besides, the code was working, so there was no real need to adjust it. With 4d76732dd749 (t/unit-tests: introduce reftable library, 2024-09-09), however, the `UNIT_TEST_OBJS` list became a trio, and the CMake definition has to be adjusted again. Now that we can use the `parse_makefile_for_sources()` function without many complications, let's do that.
