|
|
#
|
|
# Check if function is available for linking, first without extra libraries, and
|
|
# then, if not found that way, linking in each optional library as well. This
|
|
# function is similar to autotools AC_SEARCH_LIBS.
|
|
#
|
|
# If the function if found, this will define <var>.
|
|
#
|
|
# If the function was only found by linking in an additional library, this
|
|
# will define NEED_LIB_LIBX, where LIBX is the one of lib1 to libn that
|
|
# makes the function available, in uppercase.
|
|
#
|
|
# The following variables may be set before calling this macro to
|
|
# modify the way the check is run:

|
