+How to build SimGear
+====================
+
+SimGear uses the CMake build system to generate a platform-specific
+build environment.  CMake reads the CMakeLists.txt files that you'll
+find throughout the source directories, checks for installed
+dependencies and then generates the appropriate build system.
+
+If you don't already have CMake installed on your system you can grab
+it from http://www.cmake.org, use version 2.6.4 or later.
+
+Under unices (i.e. Linux, Solaris, Free-BSD, HP-Ux, OSX) use the cmake
+or ccmake command-line utils. Preferably, create an out-of-source
+build directory and run cmake or ccmake from there. The advantage to
+this approach is that the temporary files created by CMake won't
+clutter the source directory, and also makes it possible to have
+multiple independent build targets by creating multiple build
+directories. In a directory alongside the SimGear source directory
+use:
+
+    mkdir sgbuild
+    cd sgbuild
+    cmake ../simgear -DCMAKE_BUILD_TYPE=Release
+    make
+    sudo make install
+
+
+Build Dependencies
+==================
+SimGear depends on a number of 3rd party libraries, the most notable
+being:
+
+* OpenSceneGraph (OSG) - see README.OSG
+* zlib compression library - see README.zlib
+* Open Audio Library (OpenAL) - see README.OpenAL
+* Subversion Client Library (optional dependency)
+

+* README.msvc

+SimGear - Simulator Construction Tools
+======================================
+http://www.flightgear.org
+
+SimGear is a set of open-source libraries designed to be used as building
+blocks for quickly assembling 3d simulations, games, and visualization
+applications.
+
+SimGear is developed by the FlightGear project and also provides the base
+for the FlightGear Flight Simulator.
+
+Source code for SimGear is released under the GNU Library General Public
+License (LGPL) - see COPYING for license details.

+Getting started with CMake
+==========================
+
+(These instructions apply to Unix-like systems, including Cygwin and Mac. To
+build using Visual Studio or some other IDE supported by CMake, most of the
+information below still applies. Otherwise see
+http://wiki.flightgear.org/Building_Flightgear for Windows specific build
+instructions.)
+
+Always compile in a separate directory to the code. For example, if the
+code (eg, from Git) is at /home/curt/projects/simgear, you might create
+/home/curt/projects/sgbuild. Change into the new directory, and run
+
+    cmake ../simgear
+
+To generate standard Unix Makefiles in sgbuild.
+
+Probably you want to specify an install prefix:
+
+    cmake ../simgear -DCMAKE_INSTALL_PREFIX=/usr
+
+Note the install prefix is automatically searched for required libraries
+and header files, so if you install OpenSceneGraph to the same prefix,
+most configuration options are unnecessary.
+
+If for some reason you have a dependency (or several) at a different prefix,
+you can specify one or more via CMAKE_PREFIX_PATH:
+
+    cmake ../simgear -DCMAKE_PREFIX_PATH="/opt/local;/opt/fgfs"
+
+(note the use of semi-colons to specify multiple prefix paths)
+
+Standard prefixes are searched automatically (/usr, /usr/local, /opt/local)
+
+Most dependencies also expose an environment variable to specify their
+installation directory explicitly eg OSG_DIR. Any of the methods
+described above will work, but specifying an INSTALL_PREFIX or PREFIX_PATH is
+usually simpler.
+
+By default, we select a release build. To create a debug build, use
+
+    cmake ../simgear -DCMAKE_BUILD_TYPE=Debug
+
+(or MinSizeRel, or RelWithDbg)
+
+Debug builds will automatically use corresponding debug builds of required
+libraries, if they are available. For example you can install debug builds of
+OpenSceneGraph, and a debug SimGear build will use them.
+
+(Debug builds of libraries have the 'd' suffix by default - Release builds
+have no additional suffix)
+
+Note most IDE projects (eg Xcode and Visual Studio) support building all the
+build types from the same project, so you can omit the CMAKE_BUILD_TYPE option
+when running cmake, and simply pick the build configuration as normal in the
+IDE.
+
+It's common to have several build directories with different build
+configurations, eg
+
+    /home/curt/projects/simgear (the git clone)
+    /home/curt/projects/sgdebug
+    /home/curt/projects/sgrelease
+    /home/curt/projects/sg-with-svn-osg
+
+To set an optional feature, do
+
+    cmake ../simgear -DFEATURE_NAME=ON
+
+(or 'OFF' to disable )
+
+To see the variables that can be configured / are currently defined, you can
+run one of the GUI front ends, or the following command:
+
+    cmake ../simgear -L
+
+Add 'A' to see all the options (including advanced options), or 'H' to see
+the help for each option (similar to running configure --help under autoconf):
+
+    cmake ../simgear -LH
+
+
+Build Targets
+=============
+
+For a Unix makefile build, 'make dist', 'make uninstall' and 'make test' are
+all available and should work as expected. 'make clean' is also as normal,
+but there is *no* 'make distclean' target. The equivalent is to completely
+remove your build directory, and start with a fresh one.
+
+Adding new files to the build
+
+Add source files to the SOURCES list, and headers to the HEADERS list. Note
+technically you only need to add source files, but omitting headers confuses
+project generation and distribution / packaging targets.
+
+For target conditional files, you can append to the SOURCES or HEADERS lists
+inside an if() test, for example:
+
+    if(APPLE)
+        list(APPEND SOURCES extraFile1.cxx extraFile2.cxx)
+    endif()
+
+Setting include directories
+
+In any CMakeList.txt, you can do the following:
+
+    include_directories(${PROJECT_SOURCE_DIR}/some/path)
+
+For example, this can be done in particular subdirectory, or at the project
+root, or an intermediate level.
+
+Setting target specific compile flags, includes or defines
+
+Use set_target_property(), for example
+
+    set_target_property(fgfs PROPERTIES
+            COMPILE_DEFINITIONS FOO BAR=1)
+
+You can set a property on an individual source file:
+
+    set_property(SOURCE myfile.cxx PROPERTY COMPILE_FLAGS "-Wno-unsigned-compare")
+
+Detecting Features / Libraries
+
+For most standard libraries (Gtk, wxWidget, Python, GDAL, Qt, libXml, Boost),
+cmake provides a standard helper. To see the available modules, run:
+
+     cmake --help-module-list
+
+In the root CMakeLists file, use a statement like:
+
+    find_package(OpenGL REQUIRED)
+
+Each package helper sets various variables such aaa_FOUND, aaa_INCLUDE_DIR,
+and aaa_LIBRARY. Depending on the complexity of the package, these variables
+might have different names (eg, OPENSCENEGRAPH_LIBRARIES).
+
+If there's no standard helper for a library you need, find a similar one, copy
+it to CMakeModules/FindABC.cmake, and modify the code to fit. Generally this
+is pretty straightforward. The built-in modules reside in the Cmake 'share'
+directory, eg /usr/share/cmake/modules on Unix systems.
+
+Note libraries support by pkg-config can be handled directly, with no need
+to create a custom FindABC helper.
+
+Adding a new executable target
+
+    add_executable(myexecutable ${SOURCES} ${HEADERS})
+    target_link_libraries(myexecutable .... libraries ... )
+    install(TARGETS myexecutable RUNTIME DESTINATION bin)
+
+(If the executable should not be installed, omit the final line above)
+
+If you add an additional line
+
+    add_test(testname ${EXECUTABLE_OUTPUT_PATH}/myexecutable)
+
+Then running 'make test' will run your executable as a unit test. The
+executable should return either a success or failure result code.
