创建一个临时构建目录，例如build_cmake。因此所有的构建文件都在这个文件夹中。

然后在主CMake文件中添加以下命令。

add_custom_target(clean-all
    rm -rf *
)

因此，在编译时

cmake ..

和清洁做:

make clean-all

CMake官方常见问题解答说明:

Some build trees created with GNU autotools have a "make distclean" target that cleans the build and also removes Makefiles and other parts of the generated build system. CMake does not generate a "make distclean" target because CMakeLists.txt files can run scripts and arbitrary commands; CMake has no way of tracking exactly which files are generated as part of running CMake. Providing a distclean target would give users the false impression that it would work as expected. (CMake does generate a "make clean" target to remove files generated by the compiler and linker.) A "make distclean" target is only necessary if the user performs an in-source build. CMake supports in-source builds, but we strongly encourage users to adopt the notion of an out-of-source build. Using a build tree that is separate from the source tree will prevent CMake from generating any files in the source tree. Because CMake does not change the source tree, there is no need for a distclean target. One can start a fresh build by deleting the build tree or creating a separate build tree.

CMake 3。X

CMake 3。X提供了一个“干净”的目标。

cmake --build C:/foo/build/ --target clean

来自3.0.2版本的CMake文档:

--clean-first  = Build target 'clean' first, then build.
                 (To clean only, use --target 'clean'.)

CMake 2。X

在cmake版本2中没有cmake clean。X

我通常在一个类似“build”的文件夹中构建项目。如果我想弄清楚，我可以rm -rf构建。

在与根目录“CMakeLists.txt”相同的目录中的“build”文件夹通常是一个不错的选择。要构建你的项目，你只需要把CMakeLists.txt文件的位置作为参数给cmake。例如:cd <location-of-cmakelists>/build && cmake…(从@ComicSansMS)

也许它有点过时，但由于这是你谷歌cmake clean时的第一个热门，我将添加这个:

因为您可以使用指定的目标在生成目录中启动生成

Cmake——构建。——目标xyz

你当然可以跑

Cmake——构建。——目标清洁

在生成的构建文件中运行干净目标。

在Git无处不在的今天，你可能会忘记CMake，而使用Git clean -d -f -x，这将删除所有不在源代码控制下的文件。

为了简化使用“源外”构建时的清理(即在构建目录中构建)，我使用以下脚本:

$ cat ~/bin/cmake-clean-build
#!/bin/bash

if [ -d ../build ]; then
    cd ..
    rm -rf build
    mkdir build
    cd build
else
    echo "build directory DOES NOT exist"
fi

每次你需要清理时，你应该从build目录中获取这个脚本:

. cmake-clean-build
