# WebKit builds ANGLE as a static library, and exports some of the
|
|
|
|
# internal header files as "public headers" in the Xcode project for
|
|
|
|
# consumption by other build targets - e.g. WebCore.
|
|
|
|
#
|
|
|
|
# The build phase which copies these headers also flattens the
|
|
|
|
# directory structure (so that "ANGLE" is the top-level directory
|
|
|
|
# containing all of them - e.g., "#include <ANGLE/gl2.h>").
|
|
|
|
#
|
|
|
|
# It isn't practical to override the include paths so drastically for
|
|
|
|
# the other build targets (like WebCore) that we could make the
|
|
|
|
# original include paths, like <GLES2/gl2.h> work. Changing them so
|
|
|
|
# their namespace is "ANGLE", which implicitly occurs during the "copy
|
|
|
|
# headers" phase, is a reasonable solution.
|
|
|
|
#
|
|
|
|
# This script processes the header files after they're copied during
|
|
|
|
# the Copy Header Files build phase, and adjusts their #includes so
|
|
|
|
# that they refer to each other. This avoids modifying the ANGLE
|
|
|
|
# sources, and allows WebCore to more easily call ANGLE APIs directly.
