+Subject: [PATCH] Update CMakeLists.txt: set required std version to gnu++14
+
+New googletest 1.13.0 defaults to gnu++14, so makes this package FTBFS when building testsuite with this error:
+
+In file included from /usr/include/gtest/gtest-message.h:57,
+                 from /usr/include/gtest/gtest-assertion-result.h:46,
+                 from /usr/include/gtest/gtest.h:64,
+                 from /build/1st/dlt-daemon-2.18.9/tests/gtest_dlt_user.cpp:27:
+/usr/include/gtest/internal/gtest-port.h:270:2: error: #error C++ versions less than C++14 are not supported.
+  270 | #error C++ versions less than C++14 are not supported.
+      |  ^~~~~
+
+Thanks Adrian Bunk <bunk@debian.org> for the report and the fix!
