Libpqxx使用CMake的未定义引用

Question

我在WSL工具栈中使用CLion（强制CMake）。

cmake_minimum_required(VERSION 3.13)
project(conana)

set(CMAKE_CXX_STANDARD 20)
include(${CMAKE_BINARY_DIR}/cmake-build-debug/conanbuildinfo.cmake)
conan_basic_setup()
set(APPEND CMAKE_PREFIX_PATH "/mnt/c/Users/b/src/libpqxx/")

set(SOURCES main.cpp)

add_executable(conana ${SOURCES})
#target_link_libraries(${project} ${CONAN_LIBS})

产生错误

感谢您的帮助。取消注释target_link_libraries会出现“不受此CMake管理”错误。

最终删除了柯南，并完成了libpqxx问题here中的解决方案。 CMakeLists.txt最终是

cmake_minimum_required(VERSION 3.13)
project(conana)

set(CMAKE_CXX_STANDARD 20)

find_library(PQXX_LIB pqxx REQUIRED)
find_library(PQ_LIB pq REQUIRED)

set(SOURCES main.cpp)

add_executable(conana ${SOURCES})
TARGET_LINK_LIBRARIES(conana ${PQXX_LIB} ${PQ_LIB})

这在连接后也立即解决了一些问题。希望这对某人有帮助。
