Rolf Eike Beer 4be6783711 read less from version headers into variables
Instead of reading the whole file using file(READ) and later matching on the
whole file use file(STRINGS ... REGEX) to get only those lines we are
interested in at all. This will make the list much smaller (good for debugging)
and also the regular expressions will need to match on much smaller strings.

Also unset the content variables once they are not used anymore.

# - Try to find Boost include dirs and libraries
# Usage of this module as follows:
#
# NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below.
# Due to Boost naming conventions and limitations in CMake this find
# module is NOT future safe with respect to Boost version numbers,
# and may break.
#
# == Using Header-Only libraries from within Boost: ==
#
# find_package( Boost 1.36.0 )
# if(Boost_FOUND)
# include_directories(${Boost_INCLUDE_DIRS})
# add_executable(foo foo.cc)
# endif()
#
#
# == Using actual libraries from within Boost: ==
#
# set(Boost_USE_STATIC_LIBS ON)
# set(Boost_USE_MULTITHREADED ON)
# set(Boost_USE_STATIC_RUNTIME OFF)
# find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )
#
# if(Boost_FOUND)
# include_directories(${Boost_INCLUDE_DIRS})
# add_executable(foo foo.cc)
# target_link_libraries(foo ${Boost_LIBRARIES})
# endif()
#
#
# The components list needs to contain actual names of boost libraries only,
# such as "date_time" for "libboost_date_time". If you're using parts of
# Boost that contain header files only (e.g. foreach) you do not need to
# specify COMPONENTS.
#
# You should provide a minimum version number that should be used. If you provide this
# version number and specify the REQUIRED attribute, this module will fail if it
# can't find the specified or a later version. If you specify a version number this is
# automatically put into the considered list of version numbers and thus doesn't need
# to be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).
#
# NOTE for Visual Studio Users:
# Automatic linking is used on MSVC & Borland compilers by default when
# #including things in Boost. It's important to note that setting
# Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
# should you need this feature. Automatic linking typically uses static
# libraries with a few exceptions (Boost.Python is one).
#
# Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
# more details. Adding a target_link_libraries() as shown in the example
# above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
# gets set to OFF. It is suggested you avoid automatic linking since it
# will make your application less portable.
#
# =========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?) ============
#
# OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a list of
# boost version numbers that should be taken into account when searching
# for Boost. Unfortunately boost puts the version number into the
# actual filename for the libraries, so this variable will certainly be needed
# in the future when new Boost versions are released.
#
# Currently this module searches for the following version numbers:
# 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1,
# 1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39, 1.39.0,
# 1.40, 1.40.0, 1.41, 1.41.0, 1.42, 1.42.0, 1.43, 1.43.0, 1.44, 1.44.0,
# 1.45, 1.45.0, 1.46, 1.46.0, 1.46.1, 1.47, 1.47.0, 1.48, 1.48.0,
# 1.49, 1.49.0, 1.50, 1.50.0, 1.51, 1.51.0, 1.52, 1.52.0,
# 1.53, 1.53.0, 1.54, 1.54.0, 1.55, 1.55.0, 1.56, 1.56.0
#
# NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS you should
# add both 1.x and 1.x.0 as shown above. Official Boost include directories
# omit the 3rd version number from include paths if it is 0 although not all
# binary Boost releases do so.
#
# set(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")
#
# ===================================== ============= ========================
#
# Variables used by this module, they can change the default behaviour and
# need to be set before calling find_package:
#
# Boost_USE_MULTITHREADED Can be set to OFF to use the non-multithreaded
# boost libraries. If not specified, defaults
# to ON.
#
# Boost_USE_STATIC_LIBS Can be set to ON to force the use of the static
# boost libraries. Defaults to OFF.
#
# Boost_NO_SYSTEM_PATHS Set to TRUE to suppress searching in system
# paths (or other locations outside of BOOST_ROOT
# or BOOST_INCLUDEDIR). Useful when specifying
# BOOST_ROOT. Defaults to OFF.
# [Since CMake 2.8.3]
#
# Boost_NO_BOOST_CMAKE Do not do a find_package call in config mode
# before searching for a regular boost install.
# This will avoid finding boost-cmake installs.
# Defaults to OFF.
# [Since CMake 2.8.6]
#
# Boost_USE_STATIC_RUNTIME If enabled, searches for boost libraries
# linked against a static C++ standard library
# ('s' ABI tag). This option should be set to
# ON or OFF because the default behavior
# if not specified is platform dependent
# for backwards compatibility.
# [Since CMake 2.8.3]
#
# Boost_USE_DEBUG_PYTHON If enabled, searches for boost libraries
# compiled against a special debug build of
# Python ('y' ABI tag). Defaults to OFF.
# [Since CMake 2.8.3]
#
# Boost_USE_STLPORT If enabled, searches for boost libraries
# compiled against the STLPort standard
# library ('p' ABI tag). Defaults to OFF.
# [Since CMake 2.8.3]
#
# Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
# If enabled, searches for boost libraries
# compiled against the deprecated STLPort
# "native iostreams" feature ('n' ABI tag).
# Defaults to OFF.
# [Since CMake 2.8.3]
#
# Other Variables used by this module which you may want to set.
#
# Boost_ADDITIONAL_VERSIONS A list of version numbers to use for searching
# the boost include directory. Please see
# the documentation above regarding this
# annoying, but necessary variable :(
#
# Boost_DEBUG Set this to TRUE to enable debugging output
# of FindBoost.cmake if you are having problems.
# Please enable this before filing any bug
# reports.
#
# Boost_DETAILED_FAILURE_MSG FindBoost doesn't output detailed information
# about why it failed or how to fix the problem
# unless this is set to TRUE or the REQUIRED
# keyword is specified in find_package().
# [Since CMake 2.8.0]
#
# Boost_COMPILER Set this to the compiler suffix used by Boost
# (e.g. "-gcc43") if FindBoost has problems finding
# the proper Boost installation
#
# Boost_THREADAPI When building boost.thread, sometimes the name of the
# library contains an additional "pthread" or "win32"
# string known as the threadapi. This can happen when
# compiling against pthreads on Windows or win32 threads
# on Cygwin. You may specify this variable and if set
# when FindBoost searches for the Boost threading library
# it will first try to match the threadapi you specify.
# For Example: libboost_thread_win32-mgw45-mt-1_43.a
# might be found if you specified "win32" here before
# falling back on libboost_thread-mgw45-mt-1_43.a.
# [Since CMake 2.8.3]
#
# Boost_REALPATH Resolves symbolic links for discovered boost libraries
# to assist with packaging. For example, instead of
# Boost_SYSTEM_LIBRARY_RELEASE being resolved to
# "/usr/lib/libboost_system.so" it would be
# "/usr/lib/libboost_system.so.1.42.0" instead.
# This does not affect linking and should not be
# enabled unless the user needs this information.
# [Since CMake 2.8.3]
#
#
# These last three variables are available also as environment variables:
# Also, note they are completely UPPERCASE, except Boost_DIR.
#
# Boost_DIR or The preferred installation prefix for searching for
# BOOST_ROOT or BOOSTROOT Boost. Set this if the module has problems finding
# the proper Boost installation.
#
# Note that Boost_DIR behaves exactly as <package>_DIR
# variables are documented to behave in find_package's
# Config mode. That is, if it is set as a -D argument
# to CMake, it must point to the location of the
# BoostConfig.cmake or Boost-config.cmake file. If it
# is set as an environment variable, it must point to
# the root of the boost installation. BOOST_ROOT and
# BOOSTROOT, on the other hand, will point to the root
# in either case.
#
# To prevent falling back on the system paths, set
# Boost_NO_SYSTEM_PATHS to true.
#
# To avoid finding boost-cmake installations, set
# Boost_NO_BOOST_CMAKE to true.
#
# BOOST_INCLUDEDIR Set this to the include directory of Boost, if the
# module has problems finding the proper Boost installation
#
# BOOST_LIBRARYDIR Set this to the lib directory of Boost, if the
# module has problems finding the proper Boost installation
#
# Variables defined by this module:
#
# Boost_FOUND System has Boost, this means the include dir was
# found, as well as all the libraries specified in
# the COMPONENTS list.
#
# Boost_INCLUDE_DIRS Boost include directories: not cached
#
# Boost_INCLUDE_DIR This is almost the same as above, but this one is
# cached and may be modified by advanced users
#
# Boost_LIBRARIES Link to these to use the Boost libraries that you
# specified: not cached
#
# Boost_LIBRARY_DIRS The path to where the Boost library files are.
#
# Boost_VERSION The version number of the boost libraries that
# have been found, same as in version.hpp from Boost
#
# Boost_LIB_VERSION The version number in filename form as
# it's appended to the library filenames
#
# Boost_MAJOR_VERSION major version number of boost
# Boost_MINOR_VERSION minor version number of boost
# Boost_SUBMINOR_VERSION subminor version number of boost
#
# Boost_LIB_DIAGNOSTIC_DEFINITIONS [WIN32 Only] You can call
# add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
# to have diagnostic information about Boost's
# automatic linking outputted during compilation time.
#
# For each component you specify in find_package(), the following (UPPER-CASE)
# variables are set. You can use these variables if you would like to pick and
# choose components for your targets instead of just using Boost_LIBRARIES.
#
# Boost_${COMPONENT}_FOUND True IF the Boost library "component" was found.
#
# Boost_${COMPONENT}_LIBRARY Contains the libraries for the specified Boost
# "component" (includes debug and optimized keywords
# when needed).
