===================
PERFORMANCE WARNING
The OS X Finder application (file indexing used by Spotlight) used a lot of CPU
during the build - an average of %f%% (100%% is 1 core). This made your build
slower.
Consider adding ".noindex" to the end of your object directory name to have
Finder ignore it. Or, add an indexing exclusion through the Spotlight System
Preferences.
