# and libraries in /usr/local/lib, the common prefix is /usr/local.
# It should also cover the case where headers and libraries are

# Our proposal expects that FIND_* commands will automatically search for
# CMAKE_PREFIX_PATH right after CMAKE_INCLUDE_PATH or CMAKE_LIBRARY_PATH.

# will have no impact.
