PROJECT( LinkLineOrder )

# This tests ensures that the order of libraries are preserved when
# they don't have dependency information, even if they are deep in the
# dependency tree.

# NoDepC depends on NoDepA which depends on NoDepB. NoDepE and NoDepF
# are dependent on each other (recursive dependency). However, CMake
# has no information about these libraries except for the order they
# are specified in One. We must make sure we don't lose that.
