hellocmake.sln 作为“ IDE 眼中的项目”。 CMAKE_CURRENT_SOURCE_DIR 表示当前源码目录的位置，例如 ~/hellocmake 。 CMAKE_CURRENT_BINARY_DIR 表示当前输出目录的位置，例如 ~/hellocmake/build 。 project ：初始化项目信息，并把当前 CMakeLists.txt 所在位置作为根 目录 和子模块的关系： PROJECT_SOURCE_DIR ：当前项目源码路径（存放 main.cpp 的地方） • PROJECT_BINARY_DIR ：当前项目输出路径（存放 main.exe 的地方） • CMAKE_SOURCE_DIR ：根项目源码路径（存放 main.cpp 的地方） • CMAKE_BINARY_DIR ：根项目输出路径（存放 main.exe 的地方） • PROJECT_IS_TOP_LEVEL 命令，将当前目录作为一个独立的子项目 这样一来 PROJECT_SOURCE_DIR 就会是子模块的源码目录而不是外层了。 这时候 CMake 会认为这个子模块是个独立的项目，会额外做一些初始化。 他的构建目录 PROJECT_BINARY_DIR 也会变成 build/< 源码相对路径 > 。 这样在 MSVC 上也会看见 build/mylib/mylib.vcxproj 的生成。 project 的初始化： LANGUAGES

What is interoperability? Don’t touch it! Glue code? Boiler plate? A nightmare? Application binary interface (ABI) Calling conventions Marshalling Was I supposed to free that? Was I not supposed made? void get_size(size_t dev, long* size); Non-C/C++ language. Caller of get_size(). C/C++ binary. Provides get_size(). gcc and clang, sizeof(long) == sizeof(size_t) MSVC, sizeof(long) == 4 Cygwin data_t get_data_from(size_t dev); How does this function fail? C++ exceptions have no universal binary contract. Meaning the consumer may not be prepared for a C++ exception – of any sort. The typical
