+Subject: [PATCH] FindGLIB2.cmake: fix static build
+
+captype, editcap and capinfos needs glib2 and its depedencies such as
+pcre otherwise static build will fail on missing references
+
+Currenttly, FindGLIB2.cmake sets GLIB2_LIBRARIES to GLIB2_LIBRARY then
+it checks for pcre library only when CMAKE_FIND_LIBRARIES_SUFFIXES is
+equal to ".a". When it is equal to ".so;.a", pcre is not added even
+if pkg-config has only found a static library.
+
+To fix this error, update FindGLIB2.cmake to append GLIB_LIBRARY to the
+GLIB2_LIBRARIES. In the UNIX context, GLIB2_LIBRARIES will contain all
+the needed dependencies returned by pkg-config

+Subject: [PATCH] CMakeLists.txt: disable rpath in static build
+
+Trying to set RPATH to a static binary results in a build failure:
+
+CMake Error at cmake_install.cmake:50 (file):
+  file RPATH_CHANGE could not write new RPATH:
+
+    /usr/lib
+
+  to the file:
+
+    /home/fabrice/br-test-pkg/br-arm-full-static/target/usr/bin/tshark
+
+  No valid ELF RPATH or RUNPATH entry exists in the file;
+
+To fix this error, do not set RPATH if ENABLE_STATIC is set by the user
