The CMAKE_C_COMPILER: aarch64-linux-gnu-gcc is not a full path and was not found in the PATH. Tell CMake where to find the compiler by setting either the environment variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

这个错误信息提示你的 CMake 找不到 aarch64-linux-gnu-gcc 编译器,可能是因为该编译器没有安装或者没有在 PATH 环境变量中设置。你可以尝试以下几种方法来解决这个问题:
1. 安装适当的编译器。你可以在命令行中运行 "which aarch64-linux-gnu-gcc" 来查看该编译器是否已经安装。
2. 设置 PATH 环境变量。你可以在命令行中运行 "export PATH=$PATH:/path/to/your/compiler" 来将编译器所在的路径添加到 PATH 环境变量中。
3. 设置 CMake 编译器路径。你可以在 CMakeLists.txt 文件中添加以下代码来指定编译器路径:
```
set(CMAKE_C_COMPILER /path/to/your/compiler)
```
请注意,这些方法中的任何一种都可能需要根据你的具体情况进行调整。

根据你提供的错误信息,看起来 CMake 在配置项目时无法找到 C 和 C++ 编译器。这可能是由于缺少路径或编译器未正确安装所致。你可以尝试以下解决方法:
1. 确保你已经正确安装了 `arm-linux-gnueabihf-gcc` 和 `arm-linux-gnueabihf-g++` 编译器。你可以通过在终端中运行 `arm-linux-gnueabihf-gcc --version` 和 `arm-linux-gnueabihf-g++ --version` 来检查它们是否已安装。
2. 如果编译器已正确安装,但仍然无法找到,请尝试使用绝对路径设置环境变量 `CC` 和 `CXX`。例如,如果编译器的完整路径为 `/path/to/arm-linux-gnueabihf-gcc` 和 `/path/to/arm-linux-gnueabihf-g++`,你可以在终端中运行以下命令:
```
export CC=/path/to/arm-linux-gnueabihf-gcc
export CXX=/path/to/arm-linux-gnueabihf-g++
```
然后再次运行 `sudo cmake ../`。
3. 如果以上方法仍然无效,你可以尝试编辑 CMakeLists.txt 文件,在文件开头添加以下内容,指定编译器的完整路径:
```
set(CMAKE_C_COMPILER "/path/to/arm-linux-gnueabihf-gcc")
set(CMAKE_CXX_COMPILER "/path/to/arm-linux-gnueabihf-g++")
```
然后保存文件并再次运行 `sudo cmake ../`。
希望这些方法能够解决你的问题。如果你有任何其他疑问,请随时提问。

这个错误提示你的 CMakeLists.txt 文件中指定的 C 编译器路径不正确。你需要设置 CMake 缓存变量 CMAKE_C_COMPILER,告诉 CMake 编译器的完整路径或者编译器名称(如果在 PATH 中)。你可以使用以下命令来设置 CMAKE_C_COMPILER 变量:
```
cmake -DCMAKE_C_COMPILER=/usr/bin/x86_64-w64-mingw32-gcc-11.2.0
```
或者在 CMakeLists.txt 中设置 CMAKE_C_COMPILER 变量:
```
set(CMAKE_C_COMPILER "/usr/bin/x86_64-w64-mingw32-gcc-11.2.0")
```
请确保编译器路径正确,否则你可能会遇到其他编译错误。
