Win32 Visual Studio 2010 Express IDE
1. install MSVC 2010 Express Version from http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express
2. install cmake and libexpat
3. get dbus sources
4. unpack dbus sources into a sub directory (referred as <dbus-src-root> later)
5. mkdir dbus-build
6. cd dbus-build
7. run
      cmake -G "Visual Studio 10" [<options, see below>] <dbus-src-root>/cmake
8a. open IDE with
      vcexpress dbus.sln
8b. for immediate build run
      vcexpress dbus.sln /build

Win32 Visual Studio 2010 Professional IDE
1. install MSVC 2010 Professional Version
2. install cmake and libexpat
3. get dbus sources
4. unpack dbus sources into a sub directory (referred as <dbus-src-root> later)
5. mkdir dbus-build
6. cd dbus-build
7. run 
      cmake -G "Visual Studio 10" [<options, see below>] <dbus-src-root>/cmake
8a. open IDE with
      devenv dbus.sln
8b. for immediate build run
      devenv dbus.sln /build

Linux
1. install cmake and libexpat
2. get dbus sources
3. unpack dbus sources into a sub directory (referred as <dbus-src-root> later)
4. mkdir dbus-build
5. cd dbus-build
6. run 
    cmake -G "<for available targets, see cmake --help for a list>" [<options, see below>] <dbus-src-root>/cmake
    make
    make install

For other compilers see cmake --help in the Generators section

Configuration flags
-------------------

When using the cmake build system the dbus-specific configuration flags that can be given 
to the cmake program are these (use -D<key>=<value> on command line). The listed values 
are the defaults (in a typical build - some are platform-specific).

// Choose the type of build, options are: None(CMAKE_CXX_FLAGS or
// CMAKE_C_FLAGS used) Debug Release RelWithDebInfo MinSizeRel.
CMAKE_BUILD_TYPE:STRING=Debug

// Include path for 3rdparty packages
CMAKE_INCLUDE_PATH:PATH=

// Library path for 3rdparty packages
CMAKE_LIBRARY_PATH:PATH=

// Install path prefix, prepended onto install directories.
CMAKE_INSTALL_PREFIX:PATH=C:/Program Files/dbus


// enable unit test code
DBUS_BUILD_TESTS:BOOL=ON

// The name of the dbus daemon executable
DBUS_DAEMON_NAME:STRING=dbus-daemon

// Disable assertion checking
DBUS_DISABLE_ASSERT:BOOL=OFF

// Disable public API sanity checking
DBUS_DISABLE_CHECKS:BOOL=OFF

// enable -ansi -pedantic gcc flags
DBUS_ENABLE_ANSI:BOOL=OFF

// build DOXYGEN documentation (requires Doxygen)
DBUS_ENABLE_DOXYGEN_DOCS:BOOL=OFF

// enable bus daemon usage statistics
DBUS_ENABLE_STATS:BOOL=OFF

// support verbose debug mode
DBUS_ENABLE_VERBOSE_MODE:BOOL=ON

// build XML  documentation (requires xmlto or meinproc4)
DBUS_ENABLE_XML_DOCS:BOOL=ON

// install required system libraries
DBUS_INSTALL_SYSTEM_LIBS:BOOL=OFF

// session bus default listening address
DBUS_SESSION_BUS_LISTEN_ADDRESS:STRING=autolaunch:

// session bus fallback address for clients
DBUS_SESSION_BUS_CONNECT_ADDRESS:STRING=autolaunch:

// system bus default address (only useful on Unix)
DBUS_SYSTEM_BUS_DEFAULT_ADDRESS:STRING=unix:path=/var/run/dbus/system_bus_socket

win32 only:
// enable win32 debug port for message output
DBUS_USE_OUTPUT_DEBUG_STRING:BOOL=OFF

gcc only:
// compile with coverage profiling instrumentation
DBUS_GCOV_ENABLED:BOOL=OFF

solaris only:
// enable console owner file 
HAVE_CONSOLE_OWNER_FILE:BOOL=ON

// Directory to check for console ownership
DBUS_CONSOLE_OWNER_FILE:STRING=/dev/console

// Linux only:
// enable inotify as dir watch backend
DBUS_BUS_ENABLE_INOTIFY:BOOL=ON

*BSD only:
// enable kqueue as dir watch backend
DBUS_BUS_ENABLE_KQUEUE:BOOL=ON

x11 only:
// Build with X11 auto launch support
DBUS_BUILD_X11:BOOL=ON


Note: The above mentioned options could be extracted after 
configuring from the output of running "<maketool> help-options" 
in the build directory. The related entries start with 
CMAKE_ or DBUS_. 


How to compile in dbus into clients with cmake
----------------------------------------------

To compile dbus library into a client application with cmake
the following cmake commands are required:

1. call find_package to find dbus package

find_package(DBus1)

2. after specifing targets link dbus into target

add_executable(test test.c)
target_link_libraries(test ${DBus1_LIBRARIES})

Adding ${DBus1_LIBRARIES} to targets also adds required dbus
include dirs and compiler definitions by default. There is
no need to add them with include_directories and add_definitions.

To compile against dbus installed in a non standard location
specify -DDBus1_DIR=<dbus-install-root>/lib[64]/cmake/DBus1
on cmake command line.
