### to compile without jemalloc, set environment variable NOJEMALLOC=1
### to compile with gcov code coverage, set environment variable WITHGCOV=1
### to compile with ASAN, set environment variables NOJEMALLOC=1, WITHASAN=1:
###   * To perform a full ProxySQL build with ASAN then execute:
###
###     ```
###     make build_deps_debug -j$(nproc) && make debug -j$(nproc) && make build_tap_test_debug -j$(nproc)
###     ```

### ** to use on-demand coredump generation feature, compile code without ASAN option (WITHASAN=0).
