# ECMSetupVersion
|
||||
# ---------------
|
||||
#
|
||||
# Handle library version information.
|
||||
#
|
||||
# ::
|
||||
#
|
||||
# ecm_setup_version(<version>
|
||||
# VARIABLE_PREFIX <prefix>
|
||||
# [SOVERSION <soversion>]
|
||||
# [VERSION_HEADER <filename>]
|
||||
# [PACKAGE_VERSION_FILE <filename> [COMPATIBILITY <compat>]] )
|
||||
#
|
||||
# This parses a version string and sets up a standard set of version variables.
|
||||
# It can optionally also create a C version header file and a CMake package
|
||||
# version file to install along with the library.
|
||||
#
|
||||
# If the ``<version>`` argument is of the form ``<major>.<minor>.<patch>``
|
||||
# (or ``<major>.<minor>.<patch>.<tweak>``), The following CMake variables are
|
||||
# set::
|
||||
#
|
||||
# <prefix>_VERSION_MAJOR - <major>
|
||||
# <prefix>_VERSION_MINOR - <minor>
|
||||
# <prefix>_VERSION_PATCH - <patch>
|
||||
# <prefix>_VERSION - <version>
|
||||
# <prefix>_VERSION_STRING - <version> (for compatibility: use <prefix>_VERSION instead)
|
||||
# <prefix>_SOVERSION - <soversion>, or <major> if SOVERSION was not given
|
||||
#
|
||||
# If CMake policy CMP0048 is not NEW, the following CMake variables will also
|
||||
# be set::
|
||||
#
|
||||
# PROJECT_VERSION_MAJOR - <major>
|
||||
# PROJECT_VERSION_MINOR - <minor>
|
||||
# PROJECT_VERSION_PATCH - <patch>
|
||||
# PROJECT_VERSION - <version>
|
||||
# PROJECT_VERSION_STRING - <version> (for compatibility: use PROJECT_VERSION instead)
|
||||
#
|
||||
# If the VERSION_HEADER option is used, a simple C header is generated with the
|
||||
# given filename. If filename is a relative path, it is interpreted as relative
|
||||
# to CMAKE_CURRENT_BINARY_DIR. The generated header contains the following
|
||||
# macros::
|
||||
#
|
||||
# <prefix>_VERSION_MAJOR - <major> as an integer
|
||||
# <prefix>_VERSION_MINOR - <minor> as an integer
|
||||
# <prefix>_VERSION_PATCH - <patch> as an integer
|
||||
# <prefix>_VERSION_STRING - <version> as a C string
|
||||
# <prefix>_VERSION - the version as an integer
|
||||
#
|
||||
# ``<prefix>_VERSION`` has ``<patch>`` in the bottom 8 bits, ``<minor>`` in the
|
||||
# next 8 bits and ``<major>`` in the remaining bits. Note that ``<patch>`` and
|
||||
# ``<minor>`` must be less than 256.
|
||||
#
|
||||
# If the PACKAGE_VERSION_FILE option is used, a simple CMake package version
|
||||
# file is created using the write_basic_package_version_file() macro provided by
|
||||
# CMake. It should be installed in the same location as the Config.cmake file of
|
||||
# the library so that it can be found by find_package(). If the filename is a
|
||||
# relative path, it is interpreted as relative to CMAKE_CURRENT_BINARY_DIR. The
|
||||
# optional COMPATIBILITY option is forwarded to
|
||||
# write_basic_package_version_file(), and defaults to AnyNewerVersion.
|
||||
#
|
||||
# If CMake policy CMP0048 is NEW, an alternative form of the command is
|
||||
# available::
|
||||
#
|
||||
# ecm_setup_version(PROJECT
|
||||
# [VARIABLE_PREFIX <prefix>]
|
||||
# [SOVERSION <soversion>]
|
||||
# [VERSION_HEADER <filename>]
|
||||
# [PACKAGE_VERSION_FILE <filename>] )
|
||||
#
|
||||
# This will use the version information set by the project() command.
|
||||
# VARIABLE_PREFIX defaults to the project name. Note that PROJECT must be the
|
||||
# first argument. In all other respects, it behaves like the other form of the
|
||||
# command.
|
||||
#
|
||||
# Since pre-1.0.0.
|
||||
#
|
||||
# COMPATIBILITY option available since 1.6.0.
