# given by _list. If the combination is found, this macro checks (using the
# Check_Function_Exists macro) whether can link against that library
# combination using the name of a routine given by _name using the linker
# flags given by _flags. If the combination of libraries is found and passes
# the link test, LIBRARIES is set to the list of complete library paths that
# have been found. Otherwise, LIBRARIES is set to FALSE.

# If _search_include is set, also checks for presence of include file given by _include
# using Check_Include_File macro
