我像这样使用CMake:
$ mkdir build && cd build
$ cmake .. && make && atf-run | atf-report
Run Code Online (Sandbox Code Playgroud)
但是要运行atf我需要一些文件(例如/ Atffile和test/Atffile),所以我正在寻找一种方法在我的构建目录中导入所有那种文件.
我试过这个:
file(COPY ${PROJECT_SOURCE_DIR}/.. DESTINATION ${PROJECT_SOURCE_DIR}/..)

我正在尝试让 Ninja 在FreeBSD 10.3上与 CMake 一起工作:
