Note

• Because tcmalloc must be linked as an object library (alwayslink in bazel) it is require to use at least CMake 3.21. See the corresponding note on https://cmake.org/cmake/help/latest/command/target_link_libraries.html#linking-object-libraries-via-target-objects
• Because tcmalloc requires at least C++17 and because it depends on abseil, it is important to make sure that abseil is also built with C++17. Otherwise you may get link time errors related to std::basic_string_view. The easiest way to achieve this is to use a CMAKE_TOOLCHAIN_FILE that sets CMAKE_CXX_STANDARD to 17 or higher.
