<!--
This is an example of how to add custom compiler/linker
arguments for a crosscompiler.
You can use such files with setting the property 'gluegen-cpptasks.file', ie:
-Dgluegen-cpptasks.file=`pwd`/lib/gluegen-cpptasks-linux-32bit.xml
In case you want to compile for 32bit on a 64bit machine,
you might also need to set the 'os.arch' to 'x86'.
Example: gluegen/make/make.gluegen.all.linux-x86.sh
