感谢所有提供帮助的人！最终起作用的是改变：

set(CMAKE_CXX_COMPILER "gcc-10")
set(CMAKE_C_COMPILER "g++-10")

到：

set(CMAKE_CXX_COMPILER "/usr/local/opt/llvm/bin/clang")
set(CMAKE_C_COMPILER "/usr/local/opt/llvm/bin/clang++")

当我构建 syc 我的 android 项目时，它是这样的

本地属性

我该如何解决这个错误？

我正在尝试在一个相对复杂的项目中编写一些 CMake 代码，并且我有一个内部包含另一个模块的模块。问题是，每当我包含我的模块时，它内部包含的模块中定义的所有功能都在全局级别可用！这实际上是用一堆我没有明确要求的函数污染了我的全局命名空间。

例如：

# CMakeLists.txt

# Include my module
include(MyModule)

# Call a function from my module
my_module_function()

# HERE IS THE PROBLEM -- functions from "AnotherModule" are visible here!
# This call works
another_module_function()

在我的模块内：

# MyModule.cmake

# Include another module
#  - This other module is written and supported by someone else so I can't modify it
#  - No functions from "AnotherModule" will be used outside of "MyModule"
include(AnotherModule)

# Define my function
function(my_module_function)

    # Call …

通过网站脚本安装 cmake 后，我收到Could not find cmake module file: CMakeDetermineVersionCompiler.cmake 。我缺少什么以及在哪里/运行什么命令来解决此问题。

安装命令：

sudo ./cmake.sh --prefix=/usr/local/ --exclude-subdir

CMakeLists.txt：

cmake_minimum_required(VERSION 3.12)

project(Hello Version 1.0)

add_executable(${PROJECT_NAME} ../src/main.cpp)

版本：cmake版本3.16.6（我也尝试了最新版本3.17.2）

操作系统：Linux Mint 19 Cinnamon
