# WriteCompilerDetectionHeader
# ----------------------------
#
# This module provides the function write_compiler_detection_header().
#
# The ``WRITE_COMPILER_DETECTION_HEADER`` function can be used to generate
# a file suitable for preprocessor inclusion which contains macros to be
# used in source code::
#
# write_compiler_detection_header(
# FILE <file>
# PREFIX <prefix>
# [OUTPUT_FILES_VAR <output_files_var> OUTPUT_DIR <output_dir>]
# COMPILERS <compiler> [...]
# FEATURES <feature> [...]
# [VERSION <version>]
# [PROLOG <prolog>]
# [EPILOG <epilog>]
# )
#
# The ``write_compiler_detection_header`` function generates the
# file ``<file>`` with macros which all have the prefix ``<prefix>``.
#
# By default, all content is written directly to the ``<file>``. The
# ``OUTPUT_FILES_VAR`` may be specified to cause the compiler-specific
# content to be written to separate files. The separate files are then
# available in the ``<output_files_var>`` and may be consumed by the caller
# for installation for example. The ``OUTPUT_DIR`` specifies a relative
# path from the main ``<file>`` to the compiler-specific files. For example:
#
# .. code-block:: cmake
#
# write_compiler_detection_header(
# FILE climbingstats_compiler_detection.h
# PREFIX ClimbingStats
# OUTPUT_FILES_VAR support_files
# OUTPUT_DIR compilers
# COMPILERS GNU Clang
# FEATURES cxx_variadic_templates
# )
# install(FILES
# ${CMAKE_CURRENT_BINARY_DIR}/climbingstats_compiler_detection.h
# DESTINATION include
# )
# install(FILES
# ${support_files}
# DESTINATION include/compilers
# )
#
#
# ``VERSION`` may be used to specify the API version to be generated.
# Future versions of CMake may introduce alternative APIs. A given
# API is selected by any ``<version>`` value greater than or equal
# to the version of CMake that introduced the given API and less
# than the version of CMake that introduced its succeeding API.
# The value of the :variable:`CMAKE_MINIMUM_REQUIRED_VERSION`
# variable is used if no explicit version is specified.
# (As of CMake version |release| there is only one API version.)
#
# ``PROLOG`` may be specified as text content to write at the start of the
# header. ``EPILOG`` may be specified as text content to write at the end
# of the header
#
# At least one ``<compiler>`` and one ``<feature>`` must be listed. Compilers
# which are known to CMake, but not specified are detected and a preprocessor
# ``#error`` is generated for them. A preprocessor macro matching
# ``<PREFIX>_COMPILER_IS_<compiler>`` is generated for each compiler
# known to CMake to contain the value ``0`` or ``1``.
#
# Possible compiler identifiers are documented with the
# :variable:`CMAKE_<LANG>_COMPILER_ID` variable.
# Available features in this version of CMake are listed in the
# :prop_gbl:`CMAKE_C_KNOWN_FEATURES` and
# :prop_gbl:`CMAKE_CXX_KNOWN_FEATURES` global properties.
#
# See the :manual:`cmake-compile-features(7)` manual for information on
# compile features.
#
# Feature Test Macros
# ===================
#
# For each compiler, a preprocessor macro is generated matching
# ``<PREFIX>_COMPILER_IS_<compiler>`` which has the content either ``0``
# or ``1``, depending on the compiler in use. Preprocessor macros for
# compiler version components are generated matching
# ``<PREFIX>_COMPILER_VERSION_MAJOR`` ``<PREFIX>_COMPILER_VERSION_MINOR``
# and ``<PREFIX>_COMPILER_VERSION_PATCH`` containing decimal values
# for the corresponding compiler version components, if defined.
#
# A preprocessor test is generated based on the compiler version
# denoting whether each feature is enabled. A preprocessor macro
# matching ``<PREFIX>_COMPILER_<FEATURE>``, where ``<FEATURE>`` is the
# upper-case ``<feature>`` name, is generated to contain the value
# ``0`` or ``1`` depending on whether the compiler in use supports the
# feature:
#
# .. code-block:: cmake
#
# write_compiler_detection_header(
# FILE climbingstats_compiler_detection.h
# PREFIX ClimbingStats
# COMPILERS GNU Clang
# FEATURES cxx_variadic_templates
# )
#
# .. code-block:: c++
#
# #if ClimbingStats_COMPILER_CXX_VARIADIC_TEMPLATES
# template<typename... T>
# void someInterface(T t...) { /* ... */ }
# #else
# // Compatibility versions
# template<typename T1>
# void someInterface(T1 t1) { /* ... */ }
# template<typename T1, typename T2>
# void someInterface(T1 t1, T2 t2) { /* ... */ }
# template<typename T1, typename T2, typename T3>
# void someInterface(T1 t1, T2 t2, T3 t3) { /* ... */ }
# #endif
#
# Symbol Macros
# =============
#
# Some additional symbol-defines are created for particular features for
# use as symbols which may be conditionally defined empty:
#
# .. code-block:: c++
#
# class MyClass ClimbingStats_FINAL
# {
# ClimbingStats_CONSTEXPR int someInterface() { return 42; }
# };
#
# The ``ClimbingStats_FINAL`` macro will expand to ``final`` if the
# compiler (and its flags) support the ``cxx_final`` feature, and the
# ``ClimbingStats_CONSTEXPR`` macro will expand to ``constexpr``
# if ``cxx_constexpr`` is supported.
#
# The following features generate corresponding symbol defines:
#
# ========================== =================================== =================
# Feature Define Symbol
# ========================== =================================== =================
# ``c_restrict`` ``<PREFIX>_RESTRICT`` ``restrict``
# ``cxx_constexpr`` ``<PREFIX>_CONSTEXPR`` ``constexpr``
# ``cxx_deleted_functions`` ``<PREFIX>_DELETED_FUNCTION`` ``= delete``
# ``cxx_extern_templates`` ``<PREFIX>_EXTERN_TEMPLATE`` ``extern``
# ``cxx_final`` ``<PREFIX>_FINAL`` ``final``
# ``cxx_noexcept`` ``<PREFIX>_NOEXCEPT`` ``noexcept``
# ``cxx_noexcept`` ``<PREFIX>_NOEXCEPT_EXPR(X)`` ``noexcept(X)``
# ``cxx_override`` ``<PREFIX>_OVERRIDE`` ``override``
# ========================== =================================== =================
#
# Compatibility Implementation Macros
# ===================================
#
# Some features are suitable for wrapping in a macro with a backward
# compatibility implementation if the compiler does not support the feature.
#
# When the ``cxx_static_assert`` feature is not provided by the compiler,
# a compatibility implementation is available via the
# ``<PREFIX>_STATIC_ASSERT(COND)`` and
# ``<PREFIX>_STATIC_ASSERT_MSG(COND, MSG)`` function-like macros. The macros
# expand to ``static_assert`` where that compiler feature is available, and
# to a compatibility implementation otherwise. In the first form, the
# condition is stringified in the message field of ``static_assert``. In
# the second form, the message ``MSG`` is passed to the message field of
# ``static_assert``, or ignored if using the backward compatibility
# implementation.
#
# The ``cxx_attribute_deprecated`` feature provides a macro definition
# ``<PREFIX>_DEPRECATED``, which expands to either the standard
# ``[[deprecated]]`` attribute or a compiler-specific decorator such
# as ``__attribute__((__deprecated__))`` used by GNU compilers.
#
# The ``cxx_alignas`` feature provides a macro definition
# ``<PREFIX>_ALIGNAS`` which expands to either the standard ``alignas``
# decorator or a compiler-specific decorator such as
# ``__attribute__ ((__aligned__))`` used by GNU compilers.
#
# The ``cxx_alignof`` feature provides a macro definition
# ``<PREFIX>_ALIGNOF`` which expands to either the standard ``alignof``
# decorator or a compiler-specific decorator such as ``__alignof__``
# used by GNU compilers.
#
# ============================= ================================ =====================
# Feature Define Symbol
# ============================= ================================ =====================
# ``cxx_alignas`` ``<PREFIX>_ALIGNAS`` ``alignas``
# ``cxx_alignof`` ``<PREFIX>_ALIGNOF`` ``alignof``
# ``cxx_nullptr`` ``<PREFIX>_NULLPTR`` ``nullptr``
# ``cxx_static_assert`` ``<PREFIX>_STATIC_ASSERT`` ``static_assert``
# ``cxx_static_assert`` ``<PREFIX>_STATIC_ASSERT_MSG`` ``static_assert``
# ``cxx_attribute_deprecated`` ``<PREFIX>_DEPRECATED`` ``[[deprecated]]``
# ``cxx_attribute_deprecated`` ``<PREFIX>_DEPRECATED_MSG`` ``[[deprecated]]``
# ============================= ================================ =====================
#
# A use-case which arises with such deprecation macros is the deprecation
# of an entire library. In that case, all public API in the library may
# be decorated with the ``<PREFIX>_DEPRECATED`` macro. This results in
# very noisy build output when building the library itself, so the macro
# may be may be defined to empty in that case when building the deprecated
# library:
#
# .. code-block:: cmake
#
# add_library(compat_support ${srcs})
# target_compile_definitions(compat_support
# PRIVATE
# CompatSupport_DEPRECATED=
# )
