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

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)。

:)

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。)

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)

清除cmake构建输出:

命令行:

$ rm -rf [folder that you builded the project]/
$ cmake --build .

Cmake:

cmake --build . --target clean
