构建dds时找不到OpenSpliceConfig.cmake或opensplice-config.cmake -tutorial-cpp-ex

Question

我正在努力学习dds。根据tutorial，附录1建议查看github中提供的名为dds- examples -cpp-ex的示例。

根据自述文件构建此示例的简单命令是cmake . && make

我执行命令

cmake . && make

在本地计算机上克隆此文件夹后，从该文件夹的cmake目录中

我得到以下错误：

CMake Error at CMakeLists.txt:28 (FIND_PACKAGE):
  By not providing "FindOpenSplice.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "OpenSplice", but CMake did not find one.

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

    OpenSpliceConfig.cmake
    opensplice-config.cmake

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

我试图在我的系统上找到OpenSpliceConfig.cmake && opensplice-config.cmake，但是没有得到任何结果。

我的问题是如何更正路径或修复此错误？

我在本地机器上运行了OpenSplice，并且直接从$OSPL_HOME/opensplice/dcps/Tutorial执行了其他示例。它们工作得很好。

我还尝试构建ch1。我在ch1/CMakeLists.txt中编辑了第二行

set(CMAKE_MODULE_PATH ../cmake)

至

set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/../cmake)

这样它就可以在CMakeLists.txt所在的根目录中找到cmake文件夹。

当我执行以下命令时，我遇到了同样的问题：

    cd ch1 && mkdir build && cd build && cmake ..

Answer 1

我在Ubuntu20.04和OpenSplice 6.10.3p1上也遇到了同样的问题

我只是在安装目录中查找了release.com文件，然后按照@Tsyvarev的建议转到每个"ch“文件夹，并从那里运行cmake . && make。

之后，CMake成功运行。
