简单地发布rm CMakeCache.txt也适用于我。

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)

我在谷歌上搜索了大约半个小时，我想到的唯一有用的东西是调用find实用程序:

# Find and then delete all files under current directory (.) that:
#  1. contains "cmake" (case-&insensitive) in its path (wholename)
#  2. name is not CMakeLists.txt
find . -iwholename '*cmake*' -not -name CMakeLists.txt -delete

此外，确保在此之前调用make clean(或您正在使用的任何CMake生成器)。

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.

我同意外部构建是最好的答案。但是当你必须在源代码内构建的时候，我写了一个Python脚本，可以在这里使用，它:

运行“make clean” 在顶级目录中删除特定的cmake生成的文件，例如CMakeCache.txt 对于每个包含CMakeFiles目录的子目录，它会删除CMakeFiles, Makefile, cmake_install.cmake。 删除所有空子目录。

试着使用: cmake——clean-first path-of-CMakeLists.txt-file -B output-dir

-clean-first:先建造目标，然后再建造。 (只清洁，使用-目标清洁。)
