target_compile_features specified unknown feature “cxx_std_14“ for target

我用cmake编译某工程时，刚开是提示我需要升级cmake版本到3.13，而我电脑当前的是3.7，于是我投机取巧把CMakeLists.txt中的版本要求给改了
#cmake_minimum_required(VERSION 3.14.1)
cmake_minimum_required(VERSION 3.6)然后再次cmake就不报cmake版本低的错误了，但是出现下面的错误
target_compile_features specified unknown feature "cxx_std_14" for target其实这个也不需要升级cmake，这个可以理解为旧版本的cmake不能识别新的语法，只需要做如下修改就好了。
add_definitions(-std=c++14) #添加这一行
#target_compile_features(${LIBRARY_TARGET_NAME} PUBLIC cxx_std_14) #注释这一行
