ubuntu中如何创建一个名为CMakeLists.txt的文件

要在Ubuntu中创建一个名为CMakeLists.txt的文件,可以按照以下步骤进行操作:
1. 在终端中打开所需目录,即您想要创建该文件的目录。
2. 输入命令"touch CMakeLists.txt"以创建一个名为"CMakeLists.txt"的空文件。
3. 使用文本编辑器(如nano)打开该文件,并添加您需要的内容。
注意:如果您的计算机中没有安装CMake,则需要使用以下命令进行安装:sudo apt-get install cmake。

CMake Error at CMakeLists.txt:41 (include): include could not find load file: FindEigen3.cmake
这个错误提示说明在 CMakeLists.txt 文件的第41行中,使用了一个名为FindEigen3.cmake 的模块文件,但是 CMake 找不到这个文件。因此,你需要安装 Eigen3 库,并确保 CMake 能够找到它。你可以尝试以下步骤:
1. 在 Ubuntu 上,你可以使用以下命令安装 Eigen3 库:
```
sudo apt-get install libeigen3-dev
```
2. 如果你已经安装了 Eigen3 库,那么可能是因为 CMake 没有找到它的安装路径。你可以通过设置 CMake 变量来告诉 CMake Eigen3 库的安装路径,例如:
```
cmake -DCMAKE_PREFIX_PATH=/path/to/eigen3 ..
```
其中 `/path/to/eigen3` 是 Eigen3 库的安装路径。
3. 如果你仍然无法解决这个问题,你可以尝试手动下载 FindEigen3.cmake 文件,并将其放置在 CMake 模块路径中。你可以通过以下命令来查看 CMake 模块路径:
```
cmake --system-information | grep CMAKE_MODULE_PATH
```
然后将 FindEigen3.cmake 文件放置在其中一个路径下即可。

这个错误可能是因为在运行CMake时,找不到名为"bobac2_description_node"的目标。这可能是因为在CMakeLists.txt文件中没有正确地定义目标或源文件。您可以检查一下CMakeLists.txt文件中的目标和源文件是否正确定义。另外,您可以尝试清理并重新构建项目,以确保没有编译错误。您也可以查看CMakeError.log和CMakeOutput.log文件,以获取更多关于错误的详细信息。
