CMake 打包可安装程序

# 设置CMake版本最低要求
cmake_minimum_required(VERSION 3.10)

# 设置项目名称和版本
project(Tutorial VERSION 3.1)

# 指定 C++ 标准
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)

# 设置编译选项
option(USE_MYMATH "Use tutorial provided math implementation" ON)

# 生成一个头文件，传递 CMake 的一些设置到源代码
configure_file(TutorialConfig.h.in TutorialConfig.h)

# 添加 MathFunctions library
# add_subdirectory(MathFunctions)
if(USE_MYMATH)
  add_subdirectory(MathFunctions)
  list(APPEND EXTRA_LIBS MathFunctions)
endif()

# 添加源码文件和生成的目标文件的名称
add_executable(Tutorial main.cpp)

# target_link_libraries(Tutorial PUBLIC MathFunctions)
target_link_libraries(Tutorial PUBLIC ${EXTRA_LIBS})

# 添加头文件查找路径
# target_include_directories(Tutorial PUBLIC 
#                             "${PROJECT_BINARY_DIR}"
#                             "${PROJECT_SOURCE_DIR}/MathFunctions"
#                         )
target_include_directories(Tutorial PUBLIC 
                            "${PROJECT_BINARY_DIR}"
)

## 安装
install(TARGETS Tutorial DESTINATION bin)
install(FILES "${PROJECT_BINARY_DIR}/TutorialConfig.h"
  DESTINATION include
)

## 测试
enable_testing()

# does the application run
add_test(NAME Runs COMMAND Tutorial 25)

# does the usage message work?
add_test(NAME Usage COMMAND Tutorial)
set_tests_properties(Usage
  PROPERTIES PASS_REGULAR_EXPRESSION "Usage:.*number"
  )

# define a function to simplify adding tests
function(do_test target arg result)
  add_test(NAME Comp${arg} COMMAND ${target} ${arg})
  set_tests_properties(Comp${arg}
    PROPERTIES PASS_REGULAR_EXPRESSION ${result}
    )
endfunction()

# do a bunch of result based tests
do_test(Tutorial 4 "4 is 2")
do_test(Tutorial 9 "9 is 3")
do_test(Tutorial 5 "5 is 2.236")
do_test(Tutorial 7 "7 is 2.645")
do_test(Tutorial 25 "25 is 5")
do_test(Tutorial -25 "-25 is (-nan|nan|0)")
do_test(Tutorial 0.0001 "0.0001 is 0.01")
