target_link_libraries和INCLUDE_DIRECTORIES属性

本文介绍了target_link_libraries和INCLUDE_DIRECTORIES属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 此代码段中cmake_minimum_required(VERSION 3.0)project(hello LANGUAGES C VERSION 0.0.1)add_library(a INTERFACE)target_include_directories(a INTERFACE /usr/local/include)add_executable(b main.c)target_link_libraries(b PUBLIC a)get_target_property(dirs b INCLUDE_DIRECTORIES)message(STATUS "dirs: ${dirs}") CMake将打印：-- dirs: dirs-NOTFOUND我要全部包含目标的目录，但显然是通过 target_link_libraries 添加的目录不知何故。如何获取目标的所有包含目录？I want all include directories of a target, but apparently those added via target_link_libraries get ignored somehow. How can I obtain all include directories of a target?推荐答案问题是，您要查找的信息仅在生成步骤。您只能通过例如 add_custom_target（） 调用，它们在编译时运行。您的 get_target_property（）和 message（）调用在CMake配置步骤中运行。The problem is that the information you are seeking is only available after the generation step. You can get those only with e.g. add_custom_target() calls, which run during compile time. Your get_target_property() and message() calls run during CMake configuration step. 免责声明：取自以下链接的问题的一些小修改：Disclaimer: Taken with small modifications from the question linked below:add_custom_command( b_lists ALL ${CMAKE_COMMAND} -E echo "b INCLUDE_DIRECTORIES: $<TARGET_PROPERTY:B,INCLUDE_DIRECTORIES>") 参考 CMake中LINK_LIBRARIES的递归列表 $ b是href = https://stackoverflow.com/questions/37900332/target-include-directories-prior-to-2-8-12> target_include_directories在2.8.12之前？Recursive list of LINK_LIBRARIES in CMaketarget_include_directories prior to 2.8.12? 这篇关于target_link_libraries和INCLUDE_DIRECTORIES属性的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
