The FGMETA scripts are optional but will help.
I would encourage people to access third party dependencies and OSG from Jenkins: you can build them if you wish, but it really is not needed. There is no advantage to doing that -- it only takes longer.

## Set <tt>"Where to build the binaries"</tt> to a new empty directory (could be anywhere and any name, for example naming it simgear-build, at the same folder location as your unzipped SimGear source folder was put).
## Set <tt>"Where to build the binaries"</tt> to the empty directory <tt>simgear-build</tt> in the BuildDirs directory.
## Press [[File:CMake GUI Configure.png]]. The first time that the project is configured, CMake will bring up a window asking you to "Specify the generator for this project" i.e. which compiler you wish to use. Select Visual Studio 14 2015 (or Visual Studio 14 2015 Win64 for 64-bit), and press Finish. CMake will now do a check on your system and will produce a preliminary build configuration.
## Press [[File:CMake GUI Configure.png]]. The first time that the project is configured, CMake will bring up a window asking you to "Specify the generator for this project" i.e. which compiler you wish to use. Select Visual Studio 16 2019 (or the respective version for your own copy of Visual Studio), and press Finish. CMake will now do a check on your system and will produce a preliminary build configuration.
## CMake adds new configuration variables in red. Some have a value ending with <tt>-NOTFOUND</tt>. These variables should receive your attention. Some errors will prevent SimGear from building and others will simply invalidate some options without causing build errors.  
## CMake adds new configuration variables in red. Some have a value ending with <tt>-NOTFOUND</tt>. These variables do not necessarily need a value. Some errors will prevent SimGear from building and others will simply invalidate some options without causing build errors and thus can be ignored.
### First check the <tt>MSVC_3RDPARTY_ROOT</tt> variable. If it is not set, chances are that there will be a lot of <tt>-NOTFOUND</tt> errors. Instead of trying to fix every error individually, set that variable to the location of the directory structure that is presented above. Then press [[File:CMake GUI Configure.png]] again.

### Also check the lines with a checkbox. These are build options and may impact the feature set of the built program.
### Set the <tt>Boost_INCLUDE_DIR</tt> variable to <tt>\Dependencies</tt>
### To pick up Boost correctly, you must add a new Cache entry with name <tt>BOOST_ROOT</tt>, type <tt>PATH</tt>, and value <tt>\Dependencies</tt>. It is '''not''' required to set Boost_DIR to any value.
### Create a second cache entry, called <tt>CMAKE_PREFIX_PATH</tt>, type <tt>PATH</tt> and value <tt>\Dependencies\install\msvc140-64\OpenSceneGraph</tt>. This will allow OSG to be picked up automatically.
### Also verify the lines with a checkbox. These are build options and may impact the feature set of the built program.
### Default options, for anything else, should more or less be suitable. One exception is to ensure OSG_FSTREAM_EXPORT_FIXED is set to true for faster linking.

## Notably, you will have to link Simgear and QT5 to CMAKE_PREFIX_PATH ''in addition to'' OSG (as with Simgear). To do this, insert the directory values with a semi-colon to separate them. for instance <tt>SGPATH;QT5PATH;OSGPATH</tt>.

=== Script compilation ===
Firstly set up the directory structure as above.  For the following scripts, the Windows environmental variable <code>MSVC_3RDPARTY_ROOT</code> must be set to the full path where this is located.
==== SimGear ====
For building SimGear with MSVC 2015 as 64-bit:
{{collapsible script
| type  = Windows batch file
| title  = The <code>.cmake.bat</code> script for configuring and compiling SimGear
| lang  = batch
| script = REM Configure.
cmake .. ^
-DMSVC_3RDPARTY_ROOT=%MSVC_3RDPARTY_ROOT% ^
-DCMAKE_INSTALL_PREFIX=%MSVC_3RDPARTY_ROOT%\install\msvc140-64\SimGear ^
-G "Visual Studio 14 2015 Win64"
REM Compile.
cmake --build . --target install
| show  = 1
}}
{{collapsible script
| type  = Windows batch file
| title  = The <code>.cmake.bat</code> script for configuring and compiling SimGear (with debugging symbols)
| lang  = batch
| script = REM Configure.
cmake .. ^
-DMSVC_3RDPARTY_ROOT=%MSVC_3RDPARTY_ROOT% ^
-DCMAKE_INSTALL_PREFIX=%MSVC_3RDPARTY_ROOT%\install\msvc140-64\SimGear ^
-G "Visual Studio 14 2015 Win64"
REM Compile.
cmake --build . --config RelWithDebInfo --target install
}}
Place the script in a new directory within the SimGear sources such as <code>build</code>.  To clean up the build files, another batch file can be used:
{{collapsible script
| type  = Windows batch file
| title  = The <code>.clean.bat</code> script for cleaning up the build
| lang  = batch
| script = @echo off
rm -rf [0-9A-Za-z]* .vs
}}
==== FlightGear ====
For building FlightGear with MSVC 2015 as 64-bit:
{{collapsible script
| type  = Windows batch file
| title  = The <code>.cmake.bat</code> script for configuring and compiling FlightGear
| lang  = batch
| script = REM Configure.
cmake .. ^
-DMSVC_3RDPARTY_ROOT=%MSVC_3RDPARTY_ROOT% ^
-DCMAKE_INSTALL_PREFIX=%MSVC_3RDPARTY_ROOT%\install\msvc140-64\FlightGear ^
-DCMAKE_PREFIX_PATH=D:\Qt\Qt5.6.2\5.6\msvc2015_64\ ^
-G "Visual Studio 14 2015 Win64"
REM Compile.
cmake --build . --target install
| conc  = Note: change the <code>CMAKE_PREFIX_PATH</code> variable to your Qt installation directory.
| show  = 1
}}

Place the script in a new directory within the FlightGear sources such as <code>build</code>.  To clean up the build files, another batch file can be used:

=== Updating ===
=== Updating ===
When updating the source from [[git]], it is usually unnecessary to restart CMake as the solution is able to reconfigure itself when CMake files are changed. Simply rebuild the solution from Visual Studio and accept the reload of updated projects. When the Simgear/FlightGear version numbers change, you do have to re-run CMake.

Simply rebuild the solution from Visual Studio and accept the reload of updated projects. When the Simgear/FlightGear version numbers change, you do have to re-configure in CMake.


It is also possible to edit CMakeList.txt files directly in Visual Studio as they also appear in the solution, and projects will be reconfigured on the next generation. To change build options or directory path, it is mandatory to use the CMake Gui. In case of problems, locate the <tt>CMakeCache.txt</tt> file in <tt>"Where to build the binaries”</tt> directory and delete it to reconfigure from scratch or use the menu item <tt>File > Delete Cache</tt>.
