# (not part of the triple-set OT/OP/OSG source), then we need to hunt
# down the OpenThreads library on the system.
# But if we are building as part of the triple-set, then we want to
# refer to the version in the triple set. But this gets harder because
# FIND_LIBRARY will fail to pick the triple set version in this case
# because the library is not yet built when running this CMake script.

# 3rd Party Dependency Stuff
# Common to all platforms:
FIND_PACKAGE(FreeType)
# Platform specific:
# (We can approach this one of two ways. We can try to FIND everything
# and simply check if we found the packages before actually building
# or we can hardcode the cases. The advantage of the former is that
# packages that are installed on platforms that don't require them
# will still get built (presuming no compatibility issues). But this
# also means modules that are redundant may get built. For example,
# OS X doesn't need GIF, JPEG, PNG, TIFF, etc because it uses QuickTime.
# Also, it will clutter the CMake menu with "NOT_FOUND".
# The downside to the latter is that it is harder to build those
# potentially redundant modules.)

# can use Quicktime.
