编译cmd_vel_mux时候给出警告如下：

CMake Warning (dev) at yujin_ocs/yocs_cmd_vel_mux/CMakeLists.txt:31 (add_dependencies):
  Policy CMP0046 is not set: Error on non-existent dependency in
  add_dependencies.  Run "cmake --help-policy CMP0046" for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

  The dependency target "geometry_msgs_gencpp" of target
  "yocs_cmd_vel_mux_nodelet" does not exist.
This warning is for project developers.  Use -Wno-dev to suppress it.

解决办法：
在 CMakeLists.txt 文件中加入下面一行：

cmake_policy(SET CMP0046 OLD)

今天遇到一个新的policy，有点奇怪，感觉老的行为更方便一点。算是cmake新版导致的一个行为改变。继续使用原来的行为。

解决思路： 通过阅读下面的出错信息，我认为这主要是由于cmake版本变更出现了一些新的操作符的引入和旧的操作符的删除，从而引起的版本不兼容，我在安装boost库时，由于boost库是一个较老的库，而我的cmake是最新版本，因此需要使得我的cmake能够向下兼容。注意下面是IN_LIST操作符出错 – Setting libLAS build type - Release – Searching for Boost 1.38+ - done CMake Warning (dev) at /usr/local

看到的警告是因为 FindCUDA 模块在新版本的 CMake 中已经被移除。为了抑制这个警告，可以在 CMakeLists.txt 文件中设置 CMP0146。如果仍然需要查找 CUDA 并进行链接，可以用 CMake 提供的官方 CUDA 包替代。确保相应地更新你的代码，以适应新的 CMake 结构。完成这些修改后，重新运行 CMake，警告就会消失了。这条指令告诉 CMake 使用新的行为，即 FindCUDA 模块不再可用。1.打开 CMakeLists.txt 文件。

引入原因 管理CMake策略设置。有关定义的策略，请参阅cmake policies（7）手册。 随着CMake的发展，为了修复bug或改进现有特性的实现，有时需要更改现有行为。 CMake策略机制旨在帮助在CMake的新版本引入行为更改时保持现有项目的构建。 每个新策略（行为变化）都会被赋予一个形式为CMP< NNNN >的标识符，其中< NNNN >是一个整数索引。 与每个策略相关的文档描述了旧的和新的行为以及引入策略的原因。 项目可以设置每个策略来选择所需的行为。 当CMak

通过使用 cmake_policy，开发者可以确保项目在不同版本的 CMake 中构建时，行为是一致的，从而避免因 CMake 版本升级而引入的潜在问题。CMake 政策用于控制 CMake 在不同版本之间的行为更改，确保项目在使用不同版本的 CMake 时行为一致。这会设置 CMake 的策略版本。通过设置策略版本，CMake 会自动为该版本之前引入的所有策略设置适当的行为。这些命令用于保存和恢复当前的策略设置，允许在 CMake 脚本的某一部分临时更改策略而不会影响到其他部分。

在CMake项目中通常存在从大量源文件构建的目标。这些文件可以分布在不同的子目录中。在此类项目中，传统方法通常要么在最顶层目录列出所有源文件，要么将源文件list储存于一个变量，并将其传递给 add_library(), add_executable() 等。在CMake 3.13中，引入了一个新的命令target_sources()，该命令提供了各种 target_xxx 命令中缺失的部分功能。本文对target_sources()命令进行详细介绍。......
