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。

使用aarch64-linux-gnu-gcc的cmakelist怎么写

在CMakeLists.txt文件中，如果你想要使用`aarch64-linux-gnu-gcc`编译器针对AArch64 Linux平台，你可以按照下面的方式编写：

cmake_minimum_required(VERSION 3.5)
project(MyProject)

# 设置构建目录
set(CMAKE_CXX_COMPILER "aarch64-linux-gnu-gcc")
set(CMAKE_C_COMPILER "aarch64-linux-gnu-gcc")

# 针对AArch64指定编译器标志
if (CMAKE_SYSTEM_NAME MATCHES "Linux" AND CMAKE_SIZEOF_VOID_P EQUAL 8) # 检查是否为64位系统
    set(CMAKE_CXX_FLAGS "-march=armv8-a -mtune=cortex-a72") # 添加AArch64特定的编译选项
    set(CMAKE_C_FLAGS "${CMAKE_CXX_FLAGS}") # 将C语言的编译选项设置得和C++一样
endif()

# 添加源文件目录和其他依赖项
set(SOURCE_DIRS src/)
add_executable(MyApp ${SOURCE_DIRS}main.cpp other_source.cpp)

# 定义其他构建配置，如安装路径等
install(TARGETS MyApp DESTINATION bin)

这个例子中，我们首先设置了CMake的C++和C编译器为`aarch64-linux-gnu-gcc`。然后检查是否为64位的Linux系统，如果是，则添加AArch64特定的编译标志。接着，指定了源文件目录，并通过`add_executable`函数创建了一个可执行文件。最后，定义了如何安装生成的可执行文件。

这是一个CMake的错误，它提示找不到C++编译器。建议你检查一下你的系统中是否安装了C++编译器，并确认它的路径是否正确。同时，你也可以通过设置环境变量CXX或者CMake缓存条目CMAKE_CXX_COMPILER来告诉CMake编译器的路径或者编译器名称。另外，CMakeLists.txt文件中还缺少cmake_minimum_required命令，你需要在文件的开头添加这个命令，以指定CMake的最低版本要求。
