Disable ThinLTO on non-Linux Cross-compiling on Linux for Mac failed with CMake parameters -DCMAKE_BUILD_TYPE=None -DENABLE_CLICKHOUSE_SELF_EXTRACTING=1 -DENABLE_TESTS=0 (see below). This happened e.g. in #51243. The problem was that ThinLTO enabled/disabled depends on ENABLE_TESTS (see the top-level CMakeLists.txt). If ENABLE_TESTS=0 then ThinLTO is activated. On Linux, building/linking works with or without ThinLTO but on Mac building/linking the self-extracting compressor binary doesn’t work if ThinLTO is on. This is quite weird, as a workaround restrict ThinLTO to Linux. ------- [185/187] Linking CXX static library base/glibc-compatibility/libglibc-compatibility.a [186/187] Linking CXX static library contrib/zstd-cmake/lib_zstd.a [187/187] Linking CXX executable utils/self-extracting-executable/pre_compressor -- Configuring done -- Generating done -- Build files have been written to: /home/ubuntu/repo/ch4/build [0/2] Re-checking globbed directories...

Disable ThinLTO on non-Linux Cross-compiling on Linux for Mac failed with CMake parameters -DCMAKE_BUILD_TYPE=None -DENABLE_CLICKHOUSE_SELF_EXTRACTING=1 -DENABLE_TESTS=0 (see below). This happened e.g. in #51243. The problem was that ThinLTO enabled/disabled depends on ENABLE_TESTS (see the top-level CMakeLists.txt). If ENABLE_TESTS=0 then ThinLTO is activated.
