ld：-lbitcoin找不到库

Question

我正在尝试将libbitcoin库添加到我的c ++项目中。我正在使用Cmake。我在这里找到了一个配置示例：Use libbitcoin in CLion。这是我的CMakeLists.txt文件：

cmake_minimum_required(VERSION 3.14)
project(vuchain)

set(CMAKE_CXX_STANDARD 11)
set(ENV{PKG_CONFIG_PATH} "/usr/local/libbitcoin/lib/pkgconfig/:$ENV{PKG_CONFIG_PATH}")

find_package(PkgConfig REQUIRED)
find_library(libbitcoin PKG_CONFIG_PATH)
pkg_check_modules(LIB_BITCOIN REQUIRED libbitcoin)

add_executable(vuchain main.cpp user.h main.h ./HASH/HASH.cpp ./HASH/HASH.h ./HASH/sha256.cpp ./HASH/sha256.h transaction.h transaction_list.h block.h HASH/sha256.cpp HASH/sha256.h blockchain.cpp blockchain.h)

target_link_libraries(vuchain PRIVATE ${LIB_BITCOIN_LIBRARIES})
target_include_directories(vuchain PRIVATE ${LIB_BITCOIN_INCLUDE_DIRS})

CMakeLists.txt在保存时不会引发任何错误，但是在编译时，出现ld: library not found for -lbitcoin错误。我在这里想念吗？

Answer 1

将IMPORTED_TARGET选项用于pkg_check_modules。此选项将生成可链接的CMake目标，并确保为您设置所有相关变量。

pkg_check_modules(LIB_BITCOIN REQUIRED IMPORTED_TARGET libbitcoin)
target_link_libraries(vuchain PRIVATE PkgConfig::LIB_BITCOIN)
