【问题】在Windows环境下，编译01-basic_E-installing时，提示找不到lib文件

【原因】在Windows中，需要为导出类或函数设置dllexport之后，才会生成lib文件。

1. 用官方给的例子。编译之后，你会发现，没有cmake_examples_inst.lib文件

解决

修改两个文件，其他文件不变

一、使用dllexport将外部需要使用到的类导出

#ifndef __HELLO_H__
#define __HELLO_H__

#ifdef HELLO_EXPORT
#define EXPORT __declspec(dllexport)
#else
#define EXPORT 
#endif

class EXPORT Hello
{
public:
    void print();
};

#endif

二、更改CMakeList.txt文件，为cmake_examples_inst库添加HELLO_EXPORT宏

cmake_minimum_required(VERSION 3.5)

project(cmake_examples_install)

############################################################
# Create a library
############################################################

#Generate the shared library from the library sources
add_library(cmake_examples_inst SHARED
    src/Hello.cpp
)

target_include_directories(cmake_examples_inst
    PUBLIC 
        ${PROJECT_SOURCE_DIR}/include
)
# 为cmake_examples_inst库添加宏HELLO_EXPORT，以便它能生成.lib文件(Windows中，dllexport之后才会生成.lib文件)
target_compile_definitions(cmake_examples_inst PRIVATE HELLO_EXPORT)

############################################################
# Create an executable
############################################################

# Add an executable with the above sources
add_executable(cmake_examples_inst_bin
    src/main.cpp
)

# link the new hello_library target with the hello_binary target
target_link_libraries( cmake_examples_inst_bin
    PRIVATE 
        cmake_examples_inst
)

############################################################
# Install
############################################################

# Binaries
install (TARGETS cmake_examples_inst_bin
    DESTINATION bin)

# Library
# Note: may not work on windows
install (TARGETS cmake_examples_inst
    LIBRARY DESTINATION lib)

# Header files
install(DIRECTORY ${PROJECT_SOURCE_DIR}/include/ 
    DESTINATION include)

# Config
install (FILES cmake-examples.conf
    DESTINATION etc)

结果
