vcpkg BOOST库填坑

vcpkg对于boost库暂时不支持find_package

解决方法

• find_library to search for the library files (.lib) and use taget_link_libraries to link them, and
• find_path to search for header files and include them with target_include_directories.
• 也就是说需要用find_library和find_path命令替换find_package
• 如果要继续使用find_package，那么可以使用CMake自定义的内部变量Boost_INCLUDE_DIRS，Boost_LIBRARIES，请参考下面的例子

例子

使用cmake的例子:

• 注意，如果boost的某个包比如asio没有链接库，那么find_package不需要COMPONENTS参数
• 另外target_include_directories，target_link_libraries和include_directories，link_libraries是不同的

cmake_minimum_required(VERSION 3.10)
set(CMAKE_TOOLCHAIN_FILE /home/xxx/snap/vcpkg/scripts/buildsystems/vcpkg.cmake)

project(a)

AUX_SOURCE_DIRECTORY(${PROJECT_SOURCE_DIR}/src SRC_LIST)
find_package(Boost REQUIRED COMPONENTS thread)
add_executable(a.out ${SRC_LIST})
target_include_directories(a.out PUBLIC ${Boost_INCLUDE_DIRS})
target_link_libraries(a.out ${Boost_LIBRARIES})
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
