[Cluster-devel] [PATCH dlm-tool 4/4] dlm_controld: use pkg-config to find corosync libs

[Alexander Aring <aahringo@redhat.com>]

Currently all corosync dependencies are hardcorded inside the
dlm_controld Makefile. We will determine those dependencies by
pkg-config. This allows us that dlm_controld can detect when the
corosync libaries are installed in a different place determined by
changing the PKG_CONFIG_PATH env variable.
