Changeset 8653 for code/branches/unity_build/cmake

Timestamp:

May 28, 2011, 10:40:10 PM (13 years ago)

Message:

Since we already have it now: use automatic full build units for external dependencies, even in "partial" mode.
That will not actually change anything except that Bullet is now built in a single unit instead of 3.
