官方手册

Set a normal, cache, or environment variable to a given value.
See the :ref:`cmake-language(7) variables <CMake Language Variables>`
documentation for the scopes and interaction of normal variables
and cache entries.

Signatures of this command that specify a ``<value>...`` placeholder
expect zero or more arguments.  Multiple arguments will be joined as
a :ref:`semicolon-separated list <CMake Language Lists>` to form the actual variable
value to be set.  Zero arguments will cause normal variables to be
unset.  See the ``unset()`` command to unset variables explicitly.

Set Normal Variable
^^^^^^^^^^^^^^^^^^^

 set(<variable> <value>... [PARENT_SCOPE])

Sets the given ``<variable>`` in the current function or directory scope.

  • include(cmake/yaml-cpp.cmake)
    加载cmake文件的
Load and run CMake code from a file or module.

 include(<file|module> [OPTIONAL] [RESULT_VARIABLE <var>]
                       [NO_POLICY_SCOPE])

Loads and runs CMake code from the file given.  Variable reads and
writes access the scope of the caller (dynamic scoping).  If ``OPTIONAL``
is present, then no error is raised if the file does not exist.  If
``RESULT_VARIABLE`` is given the variable ``<var>`` will be set to the
full filename which has been included or ``NOTFOUND`` if it failed.

If a module is specified instead of a file, the file with name
``<modulename>.cmake`` is searched first in ``CMAKE_MODULE_PATH``,
then in the CMake module directory.  There is one exception to this: if
the file which calls ``include()`` is located itself in the CMake builtin
module directory, then first the CMake builtin module directory is searched and
``CMAKE_MODULE_PATH`` afterwards.  See also policy ``CMP0017``.
  • include_directories(“${CMAKE_SOURCE_DIR}/”)
    加载头文件文件夹
Add include directories to the build.

 include_directories([AFTER|BEFORE] [SYSTEM] dir1 [dir2 ...])

Add the given directories to those the compiler uses to search for
include files.  Relative paths are interpreted as relative to the
current source directory.

The include directories are added to the ``INCLUDE_DIRECTORIES``
directory property for the current ``CMakeLists`` file.  They are also
added to the ``INCLUDE_DIRECTORIES`` target property for each
target in the current ``CMakeLists`` file.  The target property values
are the ones used by the generators.

By default the directories specified are appended onto the current list of
directories.  This default behavior can be changed by setting
``CMAKE_INCLUDE_DIRECTORIES_BEFORE`` to ``ON``.  By using
  • link_directories()
    加载库文件夹地址
Add directories in which the linker will look for libraries.

 link_directories([AFTER|BEFORE] directory1 [directory2 ...])

Adds the paths in which the linker should search for libraries.
Relative paths given to this command are interpreted as relative to
the current source directory, see ``CMP0015``.

The command will apply only to targets created after it is called.

.. versionadded:: 3.13
  The directories are added to the ``LINK_DIRECTORIES`` directory
  property for the current ``CMakeLists.txt`` file, converting relative
  paths to absolute as needed.  See the ``cmake-buildsystem(7)``
  manual for more on defining buildsystem properties.

.. versionadded:: 3.13
  • macro(safe_set_static_flag)
    内容
    endmacro()
    这个函数属于宏定义，简单的说就是出现宏的地方进行代码替换，

    官方文档：
Start recording a macro for later invocation as a command

 macro(<name> [<arg1> ...])
   <commands>
 endmacro()

Defines a macro named ``<name>`` that takes arguments named
``<arg1>``, ... Commands listed after macro, but before the
matching ``endmacro()``, are not executed until the macro
is invoked.

Per legacy, the ``endmacro()`` command admits an optional
``<name>`` argument. If used, it must be a verbatim repeat of the
argument of the opening ``macro`` command.

See the ``cmake_policy()`` command documentation for the behavior
of policies inside macros.
  • foreach(参数，循环列表)
    用于循环列表中的每一项

在这里插入图片描述
https://blog.csdn.net/wzj_110/article/details/116110014

Evaluate a group of commands for each value in a list.

 foreach(<loop_var> <items>)
   <commands>
 endforeach()

where ``<items>`` is a list of items that are separated by
semicolon or whitespace.
All commands between ``foreach`` and the matching ``endforeach`` are recorded
without being invoked.  Once the ``endforeach`` is evaluated, the recorded
list of commands is invoked once for each item in ``<items>``.
At the beginning of each iteration the variable ``<loop_var>`` will be set
to the value of the current item.

The scope of ``<loop_var>`` is restricted to the loop scope. See policy
``CMP0124`` for details.

String operations.

Synopsis
^^^^^^^^

 Search and Replace
   string(FIND <string> <substring> <out-var> [...])
   string(REPLACE <match-string> <replace-string> <out-var> <input>...)
   string(REGEX MATCH <match-regex> <out-var> <input>...)
   string(REGEX MATCHALL <match-regex> <out-var> <input>...)
   string(REGEX REPLACE <match-regex> <replace-expr> <out-var> <input>...)

 Manipulation
   string(APPEND <string-var> [<input>...])
   string(PREPEND <string-var> [<input>...])
   string(CONCAT <out-var> [<input>...])
   string(JOIN <glue> <out-var> [<input>...])

Add -D define flags to the compilation of source files.

 add_definitions(-DFOO -DBAR ...)

Adds definitions to the compiler command line for targets in the current
directory, whether added before or after this command is invoked, and for
the ones in sub-directories added after. This command can be used to add any
flags, but it is intended to add preprocessor definitions.

.. note::

  This command has been superseded by alternatives:

  * Use ``add_compile_definitions()`` to add preprocessor definitions.
  * Use ``include_directories()`` to add include directories.
  * Use ``add_compile_options()`` to add other options.
  • cmake关系操作符号

  • find_package(OpenCV REQUIRED PATHS ${OPENCV_DIR}/build/ NO_DEFAULT_PATH)
    简单的说就是用这个如果找到了.cmake文件，就不用专门写link_directories，include_directories等函数来找头文件和库文件
Find a package (usually provided by something external to the project),
and load its package-specific details.

Search Modes
^^^^^^^^^^^^

The command has two very distinct ways of conducting the search:

**Module mode**
  In this mode, CMake searches for a file called ``Find<PackageName>.cmake``,
  looking first in the locations listed in the ``CMAKE_MODULE_PATH``,
  then among the :ref:`Find Modules` provided by the CMake installation.
  If the file is found, it is read and processed by CMake.  It is responsible
  for finding the package, checking the version, and producing any needed
  messages.  Some Find modules provide limited or no support for versioning;
  check the Find module's documentation.
