+Subject: [PATCH 2/2] build.mak.in: Filter out 3rd party libraries from
+ PJ_INSTALL_LDFLAGS.
+
+This is done so users of the installed pjproject libraries do not get
+directives (provided via pkg-config file of pjproject) to link against
+pjproject's own library dependencies.
+
+* build.mak.in (THIRD_PARTY_LIBRARIES): New variable.
+(PJ_INSTALL_LDFLAGS): Filter out THIRD_PARTY_LIBRARIES.
