Linking against CurlCPP fails. CMake + MSBuild (Visual Studio 2017) #116

Closed zavodnyrichard closed 5 years ago

zavodnyrichard commented 6 years ago

Hi, I'm having problem with building my project, where I wan't use your library. I written my own CMake module for finding your library, however it doesn't work as excepted. The problem is probably somewhere else than in this CMake module, because it doesn't work with your solution (however edited to fit my needs) either (below this paragraph).

target_link_libraries(curlcpp C:\\libs\\curlcpp-1.1\\build\\src\\Debug\\curlcpp.lib)
include_directories(C:\\libs\\curlcpp-1.1\\include)

This is my CMakeLists.txt file:

cmake_minimum_required(VERSION 3.10.0)

project(curl)
add_executable(curl curl.cpp)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT")
set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /MTd")

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}")

#search for CURL and include it
set(CURL_LIBRARY "C:\\libs\\curl-7.59.0\\curl-7.59.0\\build\\Win32\\VC15\\LIB Debug\\libcurld.lib")
set(CURL_INCLUDE_DIR "C:\\libs\\curl-7.59.0\\curl-7.59.0\\include")

find_package(CURL REQUIRED)

if(CURL_FOUND)
    target_link_libraries(curl ${CURL_LIBRARIES})
    include_directories(${CURL_INCLUDE_DIRS})
endif()
#--

#search for CurlCPP and include it
set(CURLCPP_LIBRARY "C:\\libs\\curlcpp-1.1\\build\\src\\Debug\\curlcpp.lib")
set(CURLCPP_INCLUDE_DIR "C:\\libs\\curlcpp-1.1\\include")

find_package(CurlCPP REQUIRED)

if(CURLCPP_FOUND)
    target_link_libraries(curl ${CURLCPP_LIBRARIES})
    include_directories(${CURLCPP_INCLUDE_DIRS})
endif()
#--

This is my FindCurlCPP.cmake module:

#(C) 2018 Richard Závodný <zavodnyrichard@gmail.com>
#
#Output variables are:
#CURLCPP_LIBRARIES - CurlCPP library
#CURLCPP_INCLUDE_DIRS - CurlCPP header files (curl_easy.h, curl_global.h, etc.)
#CURLCPP_FOUND - Is true if CurlCPP was found
#
#Usage:
#set(CURLCPP_LIBRARY <curlcpp root directory>\\<path to curlcpp.lib>) #required only on Windows
#set(CURLCPP_INCLUDE_DIR <curlcpp root directory>\\include) #required only on Windows
#
#find_package(CurlCPP)
#
#if(CURLCPP_FOUND)
#    target_link_libraries(<your target> ${CURLCPP_LIBRARIES})
#    include_directories(${CURLCPP_INCLUDE_DIRS})
#endif()

#find the library
find_library(CURLCPP_LIBRARY NAMES curlcpp)

#find header files
find_path(CURLCPP_INCLUDE_DIR NAMES cookie.h cookie_date.h cookie_datetime.h cookie_time.h curl_config.h curl_cookie.h curl_easy.h curl_easy_info.h curl_exception.h curl_form.h curl_global.h curl_header.h curl_info.h curl_interface.h curl_ios.h curl_multi.h curl_option.h curl_pair.h curl_receiver.h curl_sender.h curl_share.h curl_utility.h)

#set CURLCPP_FOUND to TRUE if everything is ok
include(FindPackageHandleStandardArgs)
find_package_handle_standard_args(CURLCPP DEFAULT_MSG CURLCPP_LIBRARY CURLCPP_INCLUDE_DIR)

#set output vars
if(CURLCPP_FOUND)
    set(CURLCPP_LIBRARIES ${CURLCPP_LIBRARY})
    set(CURLCPP_INCLUDE_DIRS ${CURLCPP_INCLUDE_DIR})
else(CURLCPP_FOUND)
    set(CURLCPP_LIBRARIES)
    set(CURLCPP_INCLUDE_DIRS)
endif(CURLCPP_FOUND)

mark_as_advanced(CURLCPP_LIBRARIES CURLCPP_INCLUDE_DIRS)

And this is what I've done in order to build my project:

You need to link to libcurl too.

JosephP91 commented 5 years ago

You need to link libcurl as @kiwixz reported.
