+Subject: [PATCH] disable shared library target in build
+
+Disable shared library target if BUILD_SHARED_LIBS if OFF.
+
+Patch retrieved from
+https://git.buildroot.net/buildroot/tree/package/librtlsdr/0001-disable_shared_library_target_in_build.patch?h=2018.05
+
+Patch has been updated to work with 0.5.4 and to be able to keep current
+behavior of building shared and static version of library if
+BUILD_SHARED_LIBS and BUILD_STATIC_LIBS are both set.
+Moreover, if BUILD_STATIC_LIBS is OFF, only shared version of library
+will be install.
