4Subject: [PATCH] vulkan-samples: Fix reproducibility issue
5
6There is code to remove the prefix CMAKE_SOURCE_DIR from __FILENAME__ paths
7used for logging with LOGE() in the code. We need to make this match the value we use
8in the debug source remapping from CFLAGS
9
10We export the right path to use in the recipe with:
11
12EXTRA_OECMAKE = "-DCMAKE_DEBUG_SRCDIR=${TARGET_DBGSRC_DIR}/"
13
14and we then patch this into the code instead of the broken use
15of CMAKE_SOURCE_DIR since __FILENAME__ will match our path prefix
16changes.
17
18This also breaks reproducibility since the path length of the build directory
19will currently change the output!
