Like coveragescanner, ccache is a compiler wrapper.
Using the two programs together is a configuration that is neither tested nor supported by Qt.io. We do not believe there will be much performance benefit from using ccache to cache instrumented code.
However, if you really want to use CoverageScanner
with ccache, it is necessary to set the
PATH variable as follows:
Create then (as root user) the ccache wrappers for
