CMake 不检测 CXX 但检测 CPP 文件

Question

我正在尝试从 http://www.cmake.org/cmake/help/cmake_tutorial.html 学习 CMake，但在运行简单文件 tutorial.cpp 的第一步本身遇到了麻烦。

问题是当我在 CMakeLists.txt 文件中有这个命令时

add_executable(Tutorial tutorial.cpp)

它构建得很好。

但是，当我将其更改为

add_executable(Tutorial tutorial.cxx)

它给出了以下错误

-- Configuring done
CMake Error at src/CMakeLists.txt:6 (add_executable):
  Cannot find source file:

    tutorial.cxx

  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
  .hxx .in .txx


-- Build files have been written to: /home/vaisagh/workspace/Test/build

我的目录结构是这样的：

.
├── build
├── CMakeLists.txt
└── src
    ├── CMakeLists.txt
    └── tutorial.cpp

2 directories, 3 files

CMakeLists.txt

#Specify the version being used aswell as the language
cmake_minimum_required(VERSION 2.8.11)
#Name your project here
project(Tutorial)
add_subdirectory(src)

src/CMakeLists.txt

#Specify the version being used aswell as the language
cmake_minimum_required(VERSION 2.8.11)
add_executable(Tutorial tutorial.cxx)

Answer 1

Tried extensions .c .C...表示CMake尝试搜索tutorial.cxx.c、tutorial.cxx.C等。

提供给add_executable 的源文件名必须与光盘上的实际文件名匹配。

1. 将tutorial.cpp 重命名为tutorial.cxx -或-
2. 将add_executable(Tutorial tutorial.cxx) 更改为add_executable(Tutorial tutorial.cpp)
