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主要生成一个Makefile文件，可以将rm添加到干净的PHONY文件中。

例如,

[root@localhost hello]# ls
CMakeCache.txt  CMakeFiles  cmake_install.cmake  CMakeLists.txt  hello  Makefile  test
[root@localhost hello]# vi Makefile
clean:
        $(MAKE) -f CMakeFiles/Makefile2 clean
        rm   -rf   *.o   *~   .depend   .*.cmd   *.mod    *.ko   *.mod.c   .tmp_versions *.symvers *.d *.markers *.order   CMakeFiles  cmake_install.cmake  CMakeCache.txt  Makefile

当然，外部构建是Unix makefile的首选方法，但如果您使用的是其他生成器，如Eclipse CDT，它更喜欢您构建内源。在这种情况下，您需要手动清除CMake文件。试试这个:

find . -name 'CMakeCache.txt' -o -name '*.cmake' -o -name 'Makefile' -o -name 'CMakeFiles' -exec rm -rf {} +

或者，如果你已经通过shop -s globstar启用了globstar，试试这个不那么恶心的方法:

rm -rf **/CMakeCache.txt **/*.cmake **/Makefile **/CMakeFiles

我用zsxwing的答案成功解决了以下问题:

我有在多个主机上构建的源代码(在Raspberry Pi Linux板上，在VMware Linux虚拟机上，等等)。

我有一个Bash脚本，根据机器的主机名创建临时目录，就像这样:

# Get hostname to use as part of directory names
HOST_NAME=`uname -n`

# Create a temporary directory for cmake files so they don't
# end up all mixed up with the source.

TMP_DIR="cmake.tmp.$HOSTNAME"

if [ ! -e $TMP_DIR ] ; then
  echo "Creating directory for cmake tmp files : $TMP_DIR"
  mkdir $TMP_DIR
else
  echo "Reusing cmake tmp dir : $TMP_DIR"
fi

# Create makefiles with CMake
#
# Note: switch to the temporary dir and build parent 
#       which is a way of making cmake tmp files stay
#       out of the way.
#
# Note 2: to clean up cmake files, it is OK to
#        "rm -rf" the temporary directories

echo
echo Creating Makefiles with cmake ...

cd $TMP_DIR

cmake ..

# Run makefile (in temporary directory)

echo
echo Starting build ...

make

你可以这样使用:

add_custom_target(clean-cmake-files
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

// clean-all.cmake
set(cmake_generated ${CMAKE_BINARY_DIR}/CMakeCache.txt
                    ${CMAKE_BINARY_DIR}/cmake_install.cmake
                    ${CMAKE_BINARY_DIR}/Makefile
                    ${CMAKE_BINARY_DIR}/CMakeFiles
)

foreach(file ${cmake_generated})

  if (EXISTS ${file})
     file(REMOVE_RECURSE ${file})
  endif()

endforeach(file)

我通常创建一个“make clean-all”命令，在前面的例子中添加一个调用“make clean”:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

不要尝试将“clean”目标添加为依赖项:

add_custom_target(clean-all
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
   DEPENDS clean
)

因为“干净”在CMake中不是一个真正的目标，这是行不通的。

此外，你不应该使用这个“clean-cmake-files”作为任何东西的依赖:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   DEPENDS clean-cmake-files
)

因为，如果你这样做，所有的CMake文件将在clean-all完成之前被擦除，make将抛出一个搜索“CMakeFiles/clean-all.dir/build.make”的错误。因此，在任何情况下，都不能在"anything"前面使用clean-all命令:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

这也不行。

这是一个非常旧的文件夹，但是如果你完全删除了cmake-build-debug文件夹，当你使用cmake编译时，它会自动创建一个新的cmake-build-debug文件夹，里面有你需要的所有东西。尤其适用于CLion。
