-----------------------------------
Summary: ccache is ignored when using ninja generator
Key: IMPALA-8529
URL: https://issues.apache.org/jira/browse/IMPALA-8529
Project: IMPALA
Issue Type: Task
Reporter: Todd Lipcon
The CMakeLists.txt sets up ccache by using RULE_LAUNCH_PREFIX, which is only
respected by the Makefile generator. So, if we use ninja (which is generally
better at parallelism) then ccache won't kick in. Newer versions of cmake have
more explicit support for ccache that ought to also work with the ninja
generator.
