* Fix warning

* Reenable lock file test

* Rename shader cache tests and disable crashing test

* Testing

* Stop using Path::getCanonical

* Fix persistent cache lock and test

* Fix threading issues

* Move adding file dependency hashes to getEntryPointHash()

* Fix handling of #include files

* Allow specifying additional search paths for gfx testing device

* Work on shader cache tests

* Update project files
