To prevent slipping backwards in code cleanliness, configure clang to treat warnings as errors with the exception of following warnings that are still to be completely fixed:

• QT3DS-2214 -Wnoerror=unused-local-typedefs
• QT3DS-2216 -Wnoerror=inconsistent-missing-override
• QT3DS-2222 -Wnoerror=reorder
• QT3DS-2223 -Wnoerror=format
• QT3DS-2224 -Wnoerror=unused-function
• QT3DS-2227 -Wnoerror=unused-value
• QT3DS-2229 -Wnoerror=delete-non-virtual-dtor
• QT3DS-2234 -Wnoerror=unused-variable
• QT3DS-2235 -Wnoerror=overloaded-virtual
• QT3DS-2237 -Wnoerror=unused-private-field
• QT3DS-2238 -Wnoerror=comment
• QT3DS-2240 -Wnoerror=enum-compare
• QT3DS-2241 -Wnoerror=int-to-pointer-cast
• QT3DS-2242 -Wnoerror=int-to-void-pointer-cast
• QT3DS-2244 -Wnoerror=unused-lambda-capture
• QT3DS-2246 -Wnoerror=deprecated-declarations
• QT3DS-2247 -Wnoerror=pointer-bool-conversion
• QT3DS-2248 -Wnoerror=self-assign
• QT3DS-2249 -Wnoerror=tautological-compare
• QT3DS-2251 -Wnoerror=tautological-constant-out-of-range-compare
• QT3DS-TBD Wno-error=mismatched-tags
• QT3DS-TBD Wno-error=logical-op-parentheses

Also -Wnoerror=switch needs to be ignored until the fix for QT3DS-2293 is merged from 2.1 branch to master branch.
