Sets the name of the project. Additionally this sets the variables

respective values.
|
||||
Sets the name of the project and stores the name in the
|
||||
:variable:`PROJECT_NAME` variable. Additionally this sets variables
|
||||
|
||||
* :variable:`PROJECT_SOURCE_DIR`,
|
||||
:variable:`<PROJECT-NAME>_SOURCE_DIR`
|
||||
* :variable:`PROJECT_BINARY_DIR`,

|
||||
|
||||
If ``VERSION`` is specified, given components must be non-negative integers.
|
||||
If ``VERSION`` is not specified, the default version is the empty string.
|
||||
The ``VERSION`` option may not be used unless policy :policy:`CMP0048` is
|
||||
set to ``NEW``.
|
||||
|
||||
The :command:`project()` command stores the version number and its components
|
||||
in variables
|
||||
|
||||
* :variable:`PROJECT_VERSION`,
|
||||
:variable:`<PROJECT-NAME>_VERSION`
|
||||
* :variable:`PROJECT_VERSION_MAJOR`,
|
||||
:variable:`<PROJECT-NAME>_VERSION_MAJOR`
|
||||
* :variable:`PROJECT_VERSION_MINOR`,
|
||||
:variable:`<PROJECT-NAME>_VERSION_MINOR`
|
||||
* :variable:`PROJECT_VERSION_PATCH`,
|
||||
:variable:`<PROJECT-NAME>_VERSION_PATCH`
|
||||
* :variable:`PROJECT_VERSION_TWEAK`,
|
||||
:variable:`<PROJECT-NAME>_VERSION_TWEAK`
|
||||
|
||||
Variables corresponding to unspecified versions are set to the empty string
|
||||
(if policy :policy:`CMP0048` is set to ``NEW``).
|
||||
|
||||
Optionally you can specify which languages your project supports.
|
||||
Example languages are CXX (i.e. C++), C, Fortran, etc. By default C
|
||||
and CXX are enabled. E.g. if you do not have a C++ compiler, you can
|
||||
disable the check for it by explicitly listing the languages you want
|
||||
to support, e.g. C. By using the special language "NONE" all checks
|
||||
for any language can be disabled. If a variable exists called
|
||||
CMAKE_PROJECT_<projectName>_INCLUDE, the file pointed to by that
|
||||
variable will be included as the last step of the project command.
|
||||
Example languages are ``C``, ``CXX`` (i.e. C++), ``Fortran``, etc.
|
||||
By default ``C`` and ``CXX`` are enabled if no language options are
|
||||
given. Specify language ``NONE``, or use the ``LANGUAGES`` keyword
|
||||
and list no languages, to skip enabling any languages.
|
||||
|
||||
The top-level CMakeLists.txt file for a project must contain a
|
||||
literal, direct call to the project() command; loading one through the
|
||||
include() command is not sufficient. If no such call exists CMake
|
||||
will implicitly add one to the top that enables the default languages
|
||||
(C and CXX).
|
||||
If a variable exists called :variable:`CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE`,
|
||||
the file pointed to by that variable will be included as the last step of the
|
||||
project command.

CMP0048
|
||||
-------
|
||||
|
||||
The :command:`project` command manages VERSION variables.
|
||||
|
||||
CMake version 3.0.0 introduced the ``VERSION`` option of the :command:`project`
|
||||
command to specify a project version as well as the name. In order to keep
|
||||
:variable:`PROJECT_VERSION` and related variables consistent with variable
|
||||
:variable:`PROJECT_NAME` it is necessary to set the VERSION variables
|
||||
to the empty string when no ``VERSION`` is given to :command:`project`.
|
||||
However, this can change behavior for existing projects that set VERSION
|
||||
variables themselves since :command:`project` may now clear them.
|
||||
This policy controls the behavior for compatibility with such projects.
|
||||
|
||||
The OLD behavior for this policy is to leave VERSION variables untouched.
|
||||
The NEW behavior for this policy is to set VERSION as documented by the
|
||||
:command:`project` command.
|
||||
|
||||
This policy was introduced in CMake version 3.0.0.
|
||||
CMake version |release| warns when the policy is not set and uses
|
||||
OLD behavior. Use the cmake_policy command to set it to OLD or
|
||||
NEW explicitly.
