+#!/bin/bash
+# This script may be useful for developers to profile the build process
itself.
+#
+# This shell script runs CMake and make, dumping all output into a log
file.
+# It also logs the CPU usage and memory information during the build.
+# All log messages are timestamped to enable profiling.
+#
+# Dependencies:
+# - ts
+# sudo apt-get install -y libtime-duration-perl moreutils
+# - vmstat and mpstat
+# sudo apt-get install -y sysstat
+#
+# Usage: ./profile_build.sh
+# Set the CMake and make command you want to use below.
+# By default, the number of parallel make jobs is equal to the number of
+# (virtual) CPUs on the machine (nproc).
+# If CMakeLists.txt is detected, the script exits because in-source-tree
build
+# is not supported.
+# If CMakeCache.txt is detected, the script skips cmake and runs make only.
