交叉编译c / c ++ / cuda程序时尝试使用CMake

我正在尝试使用CMake交叉编译程序，但此消息失败：

/bin/sh: 1: Syntax error: ";;" unexpected

该程序可以使用原始Makefile完美编译

这是我的CMake文件：

cmake_minimum_required(VERSION 3.9)

check_language(CUDA)

endif()

很抱歉，我无法提供项目的源代码。

我是CMake的新手，我们将不胜感激！

我尝试了@squareskittles提供的解决方案，似乎可以解决/bin/sh: 1: Syntax error: ";;" unexpected问题。但是我收到了一个新错误，内容为：

c++: fatal error: no input files

但是在相应的build.make文件中，错误行写道：

/usr/bin/c++  $(CXX_DEFINES) $(CXX_INCLUDES) $(CXX_FLAGS) -o <path-to-my-cpp>/my.cpp.o -c <path-to-my-cpp>/my.cpp

感谢@squareskittles的回答，我终于了解了CMake的工作原理。实际上，CMakeLists.txt文件中有多个不正确的部分：

1. CMake自动将-c标志添加到C和C ++编译器，因此无需手动添加。

2. 与相比，最好使用add_compile_options()添加编译标志set(CMAKE_<LANG>_FLAGS ...)。

3. link_directories应该总是去之前add_library()和之后add_executable()。而是使用一种现代方法find_library()，请参见此处。

4. 我最终放弃了像在Makefile中一样手动编写多阶段编译的方法，而是在中添加了所有源文件add_executable()。CMake似乎完美地处理了不同的情况。

我的最终工作版本：
