# - Define GNU standard installation directories

# CMAKE_INSTALL_<dir> - destination for files of a given type
# CMAKE_INSTALL_FULL_<dir> - corresponding absolute path
# where <dir> is one of:
# BINDIR - user executables (bin)
# SBINDIR - system admin executables (sbin)

You *must* have OpenSceneGraph (OSG) installed to build this version of
FlightGear.
Notice that from FlightGear version 1.9.0, OSG version 2.7.8 or later
is required. Using earlier versions of OSG will yield serious
rendering bugs. If you are using an 'older' distribution, this may mean
a suitable version of OSG may not be availble through the usual package
repositories.
Notice that FlightGear 2.6.0 requires at least version 3.0.0.
You can get the latest version of OSG from:

SPECIAL INSTRUCTIONS TO BUILD UNDER WINDOWS WITH VISUAL STUDIO
==============================================================
On Windows, assumptions on the directory structure are made to automate the discovery of dependencies.
This recommended directory structure is described below:
${MSVC_3RDPARTY_ROOT} /
3rdParty / ( includes plib, fltk, zlib, libpng, libjpeg, libtiff, freetype, libsvn, gdal, ...
bin /
include /
lib /
3rdParty.x64 / ( 64 bit version )
...
boost_1_44_0 /
boost /
install /
msvc100 / ( for VS2010 32 bits, or msvc90, msvc90-64 or msvc100-64 for VS2008 32, VS2008 64 and VS2010 64 )
OpenSceneGraph / ( OSG CMake install
bin /
include /
lib /
SimGear /
include /
lib /
If you do not use the recommended structure you will need to enter paths by hand. Source and build directories can be located anywhere.
The suggested inputs to cmake are :
MSVC_3RDPARTY_ROOT : location of the above directory structure
CMAKE_INSTALL_PREFIX : ${MSVC_3RDPARTY_ROOT}/install/msvc100/FlightGear (or any variation for the compiler version described above )
1. Set up a work directory as described above.
2. Open the Cmake gui.
3. Set "Where is the source code" to wherever you put the FlightGear sources (from the released tarball or the git repository).
4. Set "Where to build the binaries" to an empty directory.
5. Press the "Configure" button. The first time that the project is configured, Cmake will bring up a window asking which compiler you wish to use. Normally just accept Cmakes suggestion, and press Finish. Cmake will now do a check on your system and will produce a preliminary build configuration.
6. Cmake adds new configuration variables in red. Some have a value ending with -NOTFOUND. These variables should receive your attention. Some errors will prevent FlightGear to build and others will simply invalidate some options without provoking build errors. First check the MSVC_3RDPARTY_ROOT variable. If it is not set, chances are that there will be a lot of -NOTFOUND errors. Instead of trying to fix every error individually, set that variable and press the "Configure" button again.
7. Also check the lines with a checkbox. These are build options and may impact the feature set of the built program.
8. Change the CMAKE_INSTALL_PREFIX to ${MSVC_3RDPARTY_ROOT}/install/msvc100/FlightGear because C:\Program Files is likely unwritable to ordinary Windows users and will integrate better with the above directory structure (this is mandatory for SimGear if you don't want to solve errors by hand).
10. Repeat the process until the "Generate" button is enabled.
11. Press the "Generate" button.
12. Start Visual Studio 2010 and load the FlightGear solution (FlightGear.sln) located in "Where to build the binaries" (point 4.)
13. Choose the "Release" build in the VS2010 "Generation" toolbar
14. Generate the solution.
15. If there are build errors, return to Cmake, clear remaining errors, "Configure" and "Generate"
16. When Visual Studio is able to build everything without errors, build the INSTALL project to put the product files in ${CMAKE_INSTALL_PREFIX}
17. Enjoy!
PS: 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. It 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 CMakeCache.txt in "Where to build the binaries” directory and delete it to reconfigure from scratch or use the menu item File->Delete Cache.

dnl *automake 1.4a (and above) use INSTALL_STRIP_FLAG and only has

dnl *autoconf 2.13 is dumb, and thinks it can use INSTALL_PROGRAM as
dnl INSTALL_SCRIPT, which breaks with automake <= 1.4
dnl *autoconf >2.13 (since 10.Apr 1999) has not that failure
dnl to clean up that mess we:
dnl +set INSTALL_PROGRAM to use INSTALL_STRIP_FLAG
dnl which cleans KDE's program with automake > 1.4;
dnl +set INSTALL_SCRIPT to only use INSTALL, to clean up autoconf's problems

# SYNOPSIS
#
# AX_BOOST_BASE([MINIMUM-VERSION])
#
# DESCRIPTION
#
# Test for the Boost C++ libraries of a particular version (or newer)
#
# If no path to the installed boost library is given the macro searchs
# under /usr, /usr/local, /opt and /opt/local and evaluates the
# $BOOST_ROOT environment variable. Further documentation is available at
# <http://randspringer.de/boost/index.html>.
#
# This macro calls:
#
# AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
#
# And sets:
#
# HAVE_BOOST
#

# Link the yasim executable against the individual object files rather

# per-object.
#
# I think that it's permissible to list the same source files more
# than once in a Makefile.am. Hopefully this doesn't break anything.
