### Describe the bug, including details regarding any error messages, version, and platform. I'm trying to build [email protected] which pulls in `mimalloc` (ARROW_MIMALLOC_BUILD_VERSION=v2.0.6). I am using the Intel OneAPI 2025.x compiler suite, which is Clang/LLVM based. This check doesn't seem to correctly detect this compiler: https://github.com/microsoft/mimalloc/blob/09a27098aa6e9286518bd9c74e6ffa7199c3f04e/CMakeLists.txt#L361 resulting in ``` -- stderr output is: icpx: error: unknown argument: '-Kc++' icpx: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Wdeprecated] make[5]: *** [CMakeFiles/mimalloc-static.dir/build.make:82: CMakeFiles/mimalloc-static.dir/src/stats.c.o] Error 1 make[4]: *** [CMakeFiles/Makefile2:90: CMakeFiles/mimalloc-static.dir/all] Error 2 make[3]: *** [Makefile:139: all] Error 2 ``` I've also reported this upstream https://github.com/microsoft/mimalloc/issues/1153 ### Component(s) C++ -- This is an automated message from the Apache Git Service.
