cmake - find_package 找不到库时在 cmake-gui 中选择路径

Question

我find_package用来查找我的项目所需的依赖项，如下所示：

find_package(CURL REQUIRED)
if(CURL_FOUND)
  include_directories(${CURL_INCLUDE_DIRS})
  target_link_libraries(${PROJECT_NAME} ${CURL_LIBRARIES})
endif()

但是，我想知道当find_package失败时如何在 cmake-gui 中为用户手动设置选项。

Answer 1

我通过CONFIG在REQUIRED.

find_package(CURL REQUIRED CONFIG)
if(CURL_FOUND)
  include_directories(${CURL_INCLUDE_DIRS})
  target_link_libraries(${PROJECT_NAME} ${CURL_LIBRARIES})
endif()
