minimum required cMake version is 3.19 and not 3.13

Using the project with cMake 3.16 fails with the error:

CMake Error at build/cppcodec-src/CMakeLists.txt:70 (set_target_properties):
  INTERFACE_LIBRARY targets may only have whitelisted properties.  The
  property "LINKER_LANGUAGE" is not allowed.

The property set on Line 70: set_target_properties(cppcodec PROPERTIES LINKER_LANGUAGE CXX)
works only with cMake version 3.19 or newer.

Is there any option to remove the property? Or should the minimum required cMake version on Line 1 be increased to cmake_minimum_required(VERSION 3.19)?

I think it is also possible to just remove the set_target_properties(cppcodec PROPERTIES LINKER_LANGUAGE CXX) line.
The project definition on Line 2 project(cppcodec CXX) already defines the language as well as the linker language.
