相关疑难解决方法(0)

我有这个CMakeLists.txt

set(Boost_USE_STATIC_LIBS   ON)
find_package(Boost REQUIRED COMPONENTS json)
include_directories(${BOOST_INCLUDE_DIRS})
target_link_libraries(<Target> PRIVATE Boost::json)

但我收到 cmake 警告

[cmake] CMake Warning at C:/Program Files/CMake/share/cmake3.20/Modules/FindBoost.cmake:2185 (message):
[cmake]   No header defined for json; skipping header check (note: header-only
[cmake]   libraries have no designated component)

该项目可以配置和构建。~~但是compile_command.json我发现实际上并没有链接到静态库，这清楚地表明它没有找到并且被编译为仅标头库。~~

编辑：我发现它实际上链接到libboost_json-mt.a生成的build.ninja文件中，所以奇怪的是 cmake 在调用中找不到静态库find_package。
