在cmake中设置curl库路径

Question

我下载了"curl library"以用于第三方应用程序.当我运行包含的cmake文件时,我收到以下错误.请帮我.我很感激:

    >     The CXX compiler identification is MSVC 18.0.30501.0

我在Windows中为"CURL_LIBRARY"设置环境变量以指向curl的库文件安装位置,但是即使cxke指示在我的系统上检测到版本7.38.0,它仍然无法找到它.

谢谢您的帮助..

编辑:cMakeLists.txt文件

  ...
# Look for required libraries
SET(requiredlibs)

FIND_PACKAGE(CURL)
IF(CURL_FOUND)
  INCLUDE_DIRECTORIES(${CURL_INCLUDE_DIR})
  SET(requiredlibs ${requiredlibs} ${CURL_LIBRARIES} )
ELSE(CURL_FOUND)
  MESSAGE(FATAL_ERROR "Could not find the CURL library and development files.")
ENDIF(CURL_FOUND)
   ...

我在Windows环境变量中设置了include和lib目录,但没有变化.

编辑:这是完整的项目文件:cmake项目.

我遇到了同样的问题,这个问题在我的搜索过程中是最重要的问题之一.所以我给出了我找到的解决方案.以下cmake让我在我的代码中使用libcurl include.希望它对某人有用.

set(CURL_LIBRARY "-lcurl") 
find_package(CURL REQUIRED) 
add_executable (curl-demo convert.cpp)
include_directories(${CURL_INCLUDE_DIR})
target_link_libraries(curl-demo ${CURL_LIBRARIES})
