我正在尝试使用CMake为我的个人项目之一构建单元测试，尽管我完全承认我对CMake还是陌生的，并且是C ++的新手，但我对如何解决此问题深感困惑。当我去构建项目时，出现以下链接器错误：

我如何：

确保并检查对象的构建是否正确？
正确指示CMake，以便链接器可以找到我的四元数（源代码）对象吗？

任何见识都会受到赞赏。

解决方法

我的错误是错误地添加了我的库：
$ {ProjectRoot} /CMakeLists.txt

cmake_minimum_required(VERSION 3.16) # version can be different
set(CMAKE_VERBOSE_MAKEFILE ON)

set(This kepler)
get_filename_component(CODE_ROOT ${CMAKE_CURRENT_SOURCE_DIR} DIRECTORY)

project(${This}) #name of your project

project(${This} C CXX)

set(CMAKE_C_STANDARD 99)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_POSITION_INDEPENDENT_CODE ON)

enable_testing()

add_subdirectory(googletest)
add_subdirectory(test)

set(Headers
    Quaternion.hpp
)

set(Sources
    Quaternion.cpp
)

add_library(${This} STATIC ${Sources} ${Headers})

我要添加一个名为 $ {THIS} 的库，它是“开普勒”而不是预期的“四元数”，所以：

add_library(Quaternion STATIC ${Sources} ${Headers})

正确告诉链接器我的库在什么地方/什么地方

AND

在Quaternion.cpp中保留了一个主要功能，该功能已被删除
