+    drop CMake older than 3.5
+    
+    It generates a warning with newer versions of CMake.
+    3.4 was released in 2015. We require C++17 with compilers only available in 2017/2018.
+    If your CMake is older than your toolchain, you have a problem.
+    
+    There's no need to support legacy CMake going forward in libebml 2.
