- since we now have three places where we need to add a -l<foo> if and only if it isn't already in something in LIBS that provides symbol bar... This commit was SVN r8370.

# OMPI_CHECK_FUNC_LIB(func, lib)

|
# ------------------------------
|
|
# Try to find function func, first with the present LIBS, second with
|
|
# lib added to LIBS. If func is found with the libraries listed in
|
|
# LIBS, no modification to LIBS is made. If func is in lib (but not
|
|
# in LIBS) then lib is added to LIBS. If func is not in lib, then
|
|
# LIBS is not modified.
