# GenerateExportHeader
|
||||
# --------------------
|
||||
#
|
||||
# Function for generation of export macros for libraries
|
||||
#
|
||||
# This module provides the function GENERATE_EXPORT_HEADER().
|
||||
#
|
||||
# The ``GENERATE_EXPORT_HEADER`` function can be used to generate a file
|
||||
# suitable for preprocessor inclusion which contains EXPORT macros to be
|
||||
# used in library classes::
|
||||
#
|
||||
# GENERATE_EXPORT_HEADER( LIBRARY_TARGET
|
||||
# [BASE_NAME <base_name>]
|
||||
# [EXPORT_MACRO_NAME <export_macro_name>]
|
||||
# [EXPORT_FILE_NAME <export_file_name>]
|
||||
# [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
|
||||
# [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
|
||||
# [STATIC_DEFINE <static_define>]
|
||||
# [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
|
||||
# [DEFINE_NO_DEPRECATED]
|
||||
# [PREFIX_NAME <prefix_name>]
|
||||
# [CUSTOM_CONTENT_FROM_VARIABLE <variable>]
|
||||
# )
|
||||
#
|
||||
#
|
||||
# The target properties :prop_tgt:`CXX_VISIBILITY_PRESET <<LANG>_VISIBILITY_PRESET>`
|
||||
# and :prop_tgt:`VISIBILITY_INLINES_HIDDEN` can be used to add the appropriate
|
||||
# compile flags for targets. See the documentation of those target properties,
|
||||
# and the convenience variables
|
||||
# :variable:`CMAKE_CXX_VISIBILITY_PRESET <CMAKE_<LANG>_VISIBILITY_PRESET>` and
|
||||
# :variable:`CMAKE_VISIBILITY_INLINES_HIDDEN`.
|
||||
#
|
||||
# By default ``GENERATE_EXPORT_HEADER()`` generates macro names in a file
|
||||
# name determined by the name of the library. This means that in the
|
||||
# simplest case, users of ``GenerateExportHeader`` will be equivalent to:
|
||||
#
|
||||
# .. code-block:: cmake
|
||||
#
|
||||
# set(CMAKE_CXX_VISIBILITY_PRESET hidden)
|
||||
# set(CMAKE_VISIBILITY_INLINES_HIDDEN 1)
|
||||
# add_library(somelib someclass.cpp)
|
||||
# generate_export_header(somelib)
|
||||
# install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
|
||||
# install(FILES
|
||||
# someclass.h
|
||||
# ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
|
||||
# )
|
||||
#
|
||||
#
|
||||
# And in the ABI header files:
|
||||
#
|
||||
# .. code-block:: c++
|
||||
#
|
||||
# #include "somelib_export.h"
|
||||
# class SOMELIB_EXPORT SomeClass {
|
||||
# ...
|
||||
# };
|
||||
#
|
||||
#
|
||||
# The CMake fragment will generate a file in the
|
||||
# ``${CMAKE_CURRENT_BINARY_DIR}`` called ``somelib_export.h`` containing the
|
||||
# macros ``SOMELIB_EXPORT``, ``SOMELIB_NO_EXPORT``, ``SOMELIB_DEPRECATED``,
|
||||
# ``SOMELIB_DEPRECATED_EXPORT`` and ``SOMELIB_DEPRECATED_NO_EXPORT``.
|
||||
# They will be followed by content taken from the variable specified by
|
||||
# the ``CUSTOM_CONTENT_FROM_VARIABLE`` option, if any.
|
||||
# The resulting file should be installed with other headers in the library.
|
||||
#
|
||||
# The ``BASE_NAME`` argument can be used to override the file name and the
|
||||
# names used for the macros:
|
||||
#
|
||||
# .. code-block:: cmake
|
||||
#
|
||||
# add_library(somelib someclass.cpp)
|
||||
# generate_export_header(somelib
|
||||
# BASE_NAME other_name
|
||||
# )
|
||||
#
|
||||
#
|
||||
# Generates a file called ``other_name_export.h`` containing the macros
|
||||
# ``OTHER_NAME_EXPORT``, ``OTHER_NAME_NO_EXPORT`` and ``OTHER_NAME_DEPRECATED``
|
||||
# etc.
|
||||
#
|
||||
# The ``BASE_NAME`` may be overridden by specifying other options in the
|
||||
# function. For example:
|
||||
#
|
||||
# .. code-block:: cmake
|
||||
#
|
||||
# add_library(somelib someclass.cpp)
|
||||
# generate_export_header(somelib
|
||||
# EXPORT_MACRO_NAME OTHER_NAME_EXPORT
|
||||
# )
|
||||
#
|
||||
#
|
||||
# creates the macro ``OTHER_NAME_EXPORT`` instead of ``SOMELIB_EXPORT``, but
|
||||
# other macros and the generated file name is as default:
|
||||
#
|
||||
# .. code-block:: cmake
|
||||
#
|
||||
# add_library(somelib someclass.cpp)
|
||||
# generate_export_header(somelib
|
||||
# DEPRECATED_MACRO_NAME KDE_DEPRECATED
|
||||
# )
|
||||
#
|
||||
#
|
||||
# creates the macro ``KDE_DEPRECATED`` instead of ``SOMELIB_DEPRECATED``.
|
||||
#
|
||||
# If ``LIBRARY_TARGET`` is a static library, macros are defined without
|
||||
# values.
|
||||
#
|
||||
# If the same sources are used to create both a shared and a static
|
||||
# library, the uppercased symbol ``${BASE_NAME}_STATIC_DEFINE`` should be
|
||||
# used when building the static library:
|
||||
#
|
||||
# .. code-block:: cmake
|
||||
#
|
||||
# add_library(shared_variant SHARED ${lib_SRCS})
|
||||
# add_library(static_variant ${lib_SRCS})
|
||||
# generate_export_header(shared_variant BASE_NAME libshared_and_static)
|
||||
# set_target_properties(static_variant PROPERTIES
|
||||
# COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)
|
||||
#
|
||||
# This will cause the export macros to expand to nothing when building
|
||||
# the static library.
|
||||
#
|
||||
# If ``DEFINE_NO_DEPRECATED`` is specified, then a macro
|
||||
# ``${BASE_NAME}_NO_DEPRECATED`` will be defined This macro can be used to
|
||||
# remove deprecated code from preprocessor output:
|
||||
#
|
||||
# .. code-block:: cmake
|
||||
#
|
||||
# option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
|
||||
# if (EXCLUDE_DEPRECATED)
|
||||
# set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
|
||||
# endif()
|
||||
# generate_export_header(somelib ${NO_BUILD_DEPRECATED})
|
||||
#
|
||||
#
|
||||
# And then in somelib:
|
||||
#
|
||||
# .. code-block:: c++
|
||||
#
|
||||
# class SOMELIB_EXPORT SomeClass
|
||||
# {
|
||||
# public:
|
||||
# #ifndef SOMELIB_NO_DEPRECATED
|
||||
# SOMELIB_DEPRECATED void oldMethod();
|
||||
# #endif
|
||||
# };
|
||||
#
|
||||
# .. code-block:: c++
|
||||
#
|
||||
# #ifndef SOMELIB_NO_DEPRECATED
|
||||
# void SomeClass::oldMethod() { }
|
||||
# #endif
|
||||
#
|
||||
#
|
||||
# If ``PREFIX_NAME`` is specified, the argument will be used as a prefix to
|
||||
# all generated macros.
|
||||
#
|
||||
# For example:
|
||||
#
|
||||
# .. code-block:: cmake
|
||||
#
|
||||
# generate_export_header(somelib PREFIX_NAME VTK_)
|
||||
#
|
||||
# Generates the macros ``VTK_SOMELIB_EXPORT`` etc.
|
||||
#

||||
# ::
|
||||
#
|
||||
# ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )
|
||||
#
|
||||
# The ``ADD_COMPILER_EXPORT_FLAGS`` function adds ``-fvisibility=hidden`` to

# :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` if supported, and is a no-op
