Add a script to test the build performance
The build_performance_measure.py may be used to compare the build time needed with cmake od meson based builds. To reduce the build time, ccache is used. Note: The tests needs to run at least 2 times to fill the ccache! Prevent cmakelint warnings too. Enable all tests and examples to have as much as possible build targets.pull/1434/head
