# This file verifies that all libraries used by the package can be found

# User-settable variables:
#
# CHECK_SHLIBS
#	Whether the check should be enabled or not.
#
#	Default value: "yes" for PKG_DEVELOPERs, "no" otherwise.
#
# Package-settable variables:
#
# CHECK_SHLIBS_SKIP
#	A list of shell patterns (like man/*) that should be excluded
#	from the check. Note that a * in a pattern also matches a slash
#	in a pathname.
#
#	Default value: empty.
#
# CHECK_SHLIBS_SUPPORTED
#	Whether the check should be enabled for this package or not.
#
#	Default value: yes
