#
# This file verifies that all libraries used by the package can be found
# at run-time.
#
# User-settable variables:
#
# CHECK_SHLIBS
#	Whether the check should be enabled or not.
#
#	Default value: "yes" for PKG_DEVELOPERs, "no" otherwise.
#
# CHECK_SHLIBS_BLACKLIST
# 	A list of regular expressions that will cause the test to fail
# 	if they are matched in the resolved runpath.  For example, set
# 	to ^/usr/lib/lib(crypto|ssl) will ensure that OpenSSL is not
# 	accidentally picked up from the OS.
#
#	Default value: empty.
#
# 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
