小编Den*_*tov的帖子

昨天遇到了如何从某个类获取所有基类的问题.例如:

class Object 
{
public:
   Object() = default;
};

class DerivedOne
   : public Object
{
public:
   DerivedOne() = default;
};

class DerivedTwo
   : public Object
   , public DerivedOne
{
public:
   DerivedTwo() = default;
};

我想在typelist => {Object,DerivedOne,Object}中获取DerivedTwo的所有基类.需要多次拒绝来自Object类的继承.

有人这样的经验或知识怎么做？

我试图找到解决方案：How to check target for build ?

考虑以下 CMake 脚本：

cmake_minimum_required(VERSION 3.5.1)
project(cppTests)

# How to check at this point the target of build
if(TARGET "cppTests")
    message(STATUS "Target is cppTests")
else()
    message(STATUS "Target is not cppTests")
endif()


message(STATUS "Target is ${TARGET}")
set(CMAKE_CXX_STANDARD 11)

set(SOURCE_FILES main.cpp)
add_executable(cppTests ${SOURCE_FILES})

然后我调用以下内容：

/home/username/Software/clion-2017.1.1/bin/cmake/bin/cmake --build /home/username/Projects/cppTests/cmake-build-debug --target cppTests -- -j 8

如何在--target选项之后检查CMake脚本中的目标cppTests？我正在Makefiles中寻找类似MAKECMDGOALS 的内容。我找到了任何有用的解决方案...
