c++ - CMake 找不到 librdkafka

问题描述

我正在尝试在使用 CMake 构建的项目中使用 Kafka。

我安装了 librdkafka-dev（版本 0.8.6-1.1）。

我还尝试从 Git 下载项目并手动构建它，这似乎是成功的。

我注意到 librdkafka/packaging/cmake 中有一个 README.md 文件，并按照它的说明，在目录中成功创建了 librdkafka 的 CMake 构建。

在我的项目中运行“cmake”命令会导致以下错误：

CMake Error at CMakeLists.txt:8 (find_package):
  By not providing "Findlibrdkafka.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "librdkafka", but CMake did not find one.

  Could not find a package configuration file provided by "librdkafka" with
  any of the following names:

    librdkafkaConfig.cmake
    librdkafka-config.cmake

  Add the installation prefix of "librdkafka" to CMAKE_PREFIX_PATH or set
  "librdkafka_DIR" to a directory containing one of the above files.  If
  "librdkafka" provides a separate development package or SDK, be sure it has
  been installed.

librdkafka 可能只是在 CMakeLists.txt 文件中查找 rdkafka 的错误包名称，但我还没有找到如何在不使用 Cppkafka 包装器的情况下将其添加到 CMake。

所以我尝试下载和构建 Cppkafka（cmake ..在其目录的文件夹内运行），它导致以下错误：

-- Build will generate a shared library. Use CPPKAFKA_BUILD_SHARED=0 to perform a static build
-- RdKafkaConfig.cmake not found. Attempting to find module instead...
-- Could NOT find RDKAFKA (missing: RdKafka_LIBRARY_DIR) 
-- Found valid rdkafka version
-- RdKafka module found.
-- Disabling tests because submodule Catch2 isn't checked out
-- Configuring done
CMake Error in src/CMakeLists.txt:
  Target "RdKafka::rdkafka" contains relative path in its
  INTERFACE_LINK_DIRECTORIES:

    "RdKafka_LIBRARY_DIR-NOTFOUND"

感谢您的任何帮助！

解决方案

这自己解决了。显然，这是 CppKafka 库的一个错误，开发人员已经解决了这个问题。
