-#  otherwise CURRENT will be "YES".  IF not CURRENT, then
-#  <UPPERCASED-Name>_DEP0, ... will be FORCED to NOTFOUND.

-#    find_path (FOO_DIR include/foo.h)

-# ResolveCompilerPaths - this module defines two macros
-#
-# RESOLVE_LIBRARIES (XXX_LIBRARIES LINK_LINE)
-#  This macro is intended to be used by FindXXX.cmake modules.
-#  It parses a compiler link line and resolves all libraries
-#  (-lfoo) using the library path contexts (-L/path) in scope.
-#  The result in XXX_LIBRARIES is the list of fully resolved libs.
-#  Example:
-#
-#    RESOLVE_LIBRARIES (FOO_LIBRARIES "-L/A -la -L/B -lb -lc -ld")
-#
-#  will be resolved to
-#
-#    FOO_LIBRARIES:STRING="/A/liba.so;/B/libb.so;/A/libc.so;/usr/lib/libd.so"
-#
-#  if the filesystem looks like
-#
-#    /A:       liba.so         libc.so
-#    /B:       liba.so libb.so
-#    /usr/lib: liba.so libb.so libc.so libd.so
-#
-#  and /usr/lib is a system directory.
-#
-#  Note: If RESOLVE_LIBRARIES() resolves a link line differently from
-#  the native linker, there is a bug in this macro (please report it).
-#
-# RESOLVE_INCLUDES (XXX_INCLUDES INCLUDE_LINE)
-#  This macro is intended to be used by FindXXX.cmake modules.
-#  It parses a compile line and resolves all includes
-#  (-I/path/to/include) to a list of directories.  Other flags are ignored.
-#  Example:
-#
-#    RESOLVE_INCLUDES (FOO_INCLUDES "-I/A -DBAR='\"irrelevant -I/string here\"' -I/B")
-#
-#  will be resolved to
-#
-#    FOO_INCLUDES:STRING="/A;/B"
-#
-#  assuming both directories exist.
-#  Note: as currently implemented, the -I/string will be picked up mistakenly (cry, cry)
