=E2=80=8BYou need to actually set this to a value, in order for the variabl=
e to be
defined.
WITH_CCACHE_BUILD=3Dyes
WITH_CCACHE_BUILD=3Dsomething
WITH_CCACHE_BUILD=3Dwhatever
It doesn't matter what it's set to, but it has to be set to something.=E2=

=E2=80=8BThis line here checks if the variable is defined (meaning, that it=
is set
to something), and if it is, then the code after it enabled CCACHE.=E2=80=
