Question

我使用以下命令编译了boost：

b2.exe link=shared runtime-link=shared address-model=32 variant=release --layout=system --stagedir=./stage/win32

我正在为我自己的CMake加载Boost组件，

find_path(Boost_INCLUDE_DIR NAMES boost/config.hpp PATHS ${CMAKE_CURRENT_SOURCE_DIR}/../external/boost_1_69_0)
message("${Boost_INCLUDE_DIR}")

add_library(Boost INTERFACE IMPORTED GLOBAL)
set_target_properties(Boost PROPERTIES INTERFACE_INCLUDE_DIRECTORIES ${Boost_INCLUDE_DIR})

find_library(Boost_filesystem_LIBRARY NAMES boost_filesystem PATHS ${CMAKE_CURRENT_SOURCE_DIR}/../external/boost_1_69_0/stage/win32/lib)
message("${Boost_filesystem_LIBRARY}")

add_library(Boost_filesystem UNKNOWN IMPORTED GLOBAL)
set_target_properties(Boost_filesystem PROPERTIES INTERFACE_INCLUDE_DIRECTORIES ${Boost_INCLUDE_DIR})
set_target_properties(Boost_filesystem PROPERTIES IMPORTED_LOCATION ${Boost_filesystem_LIBRARY})
target_link_libraries(Boost INTERFACE Boost_filesystem)

调用CMake时：

C:/bla/SW/cmake-template/external/boost_1_69_0
C:/bla/SW/cmake- 
template/external/boost_1_69_0/stage/win32/lib/boost_filesystem.lib

我不明白，它为什么试图链接到libboost_filesystem-vc141-mt-gd-x32-1_69.lib而不是boost_filesystem.lib？

该链接来自某些Boost库的自动墨水功能。您可以在Boost Config library中调整自动链接以使用适当的命名see宏来控制它。或者，您也可以关闭与Boost Config docs中提到的BOOST_ALL_NO_LIB宏的自动链接。

boost b2 --layout = system使用CMake在Visual Studio上导致LNK1104错误
