+#
+# Author:
+#     Martin Beaudoin, Hydro-Quebec, (2014)
+#

+
+# We grab the value of WM_THIRD_PARTY and WM_OPTIONS from the environment variable
+%{expand:%%define _WM_THIRD_PARTY_DIR %(echo $WM_THIRD_PARTY_DIR)}
+%{expand:%%define _WM_OPTIONS         %(echo $WM_OPTIONS)}
+
+# Disable the generation of debuginfo packages
+%define debug_package %{nil}
+
+# The topdir needs to point to the $WM_THIRD_PARTY/rpmbuild directory
+%define _topdir	 	%{_WM_THIRD_PARTY_DIR}/rpmBuild
+%define _tmppath	%{_topdir}/tmp
+
+# Will install the package directly $WM_THIRD_PARTY_DIR
+#   Some comments about package relocation:
+#   By using this prefix for the Prefix:  parameter in this file, you will make this
+#   package relocatable.
+#
+#   This is fine, as long as your software is itself relocatable.
+#
+#   Simply take note that libraries built with libtool are not relocatable because the
+#   prefix we specify will be hard-coded in the library .la files.
+#   Ref: http://sourceware.org/autobook/autobook/autobook_80.html
+#
+#   In that case, if you ever change the value of the $WM_THIRD_PARTY_DIR, you will
+#   not be able to reutilize this RPM, even though it is relocatable. You will need to
+#   regenerate the RPM.
