The top-level nodes live inside an <xml> node, and can be:
set - Sets a "define", define being a general variable.<setname="name"value="1"/>
setenv - Sets an hxcpp define and an environment variable for child processes.<setenvname="name"value="1"/>
unset - Unsets a define. if="name" will no longer be true.<unsetname="name"/>
setup - Used internally to call custom setup code to find SDKs etc.<setupname="androidNdk|blackberry|msvc|pdbserver|mingw|emscripten|nvcc"/>
echo - Prints a value to console. Good for debugging.<echovalue="text"/>
error - Prints a value to console and forces an error. Good for checking prerequisites.<errorvalue="error message"/>
pleaseUpdateHxcppTool - Used to tell people updating git version that they need to recompile the build tool.<pleaseUpdateHxcppToolversion="1"/>
path - Adds a directory to the exe search path.<pathname="directory_to_add"/>
mkdir - Creates a directory.<mkdirname="directory"/>
section - Groups blocks of elements - usually ones that all respect the same if/unless condition.<sectionname="id"/>...</section>
copy - Copies a file when the node is parsed.<copyto="destination"from="src"/>
import/include - Reads XML from another file. import resets the relative base to the new file, include does not.
noerror - when true, allows the file to be missing. (optional)section - only read the named section from the XML file. Used by hxcpp_config.xml. (optional)<importname="filename"section="filter"noerror="true"/><includename="filename"section="filter"noerror="true"/>
pragma - Only include build file once, even with multiple include statements.<pragmaonce="true"/>
nvccflag - Adds flag to all nvcc compiles.<nvccflagname="?name"value="-IincludePath"/>
nvcclinkflag - Adds flag when linking with nvcc code.<nvcclinkflagname="?name"value="-arch=sm_30"/>
files - Defines a file group, and sets default tags.
dir - directory to which the filenames in the group are relative.tags - comma-separated list of tags.<filesdir="dir"name="name"tags="tag1,tag2,tag3">...</files>
target - Defines a target, and sets its toolid (link mode) and output name.<targetname="name"overwrite="true"append="true"tool="linker"toolid="${haxelink}"output="filename">...</target>
copyFile - Copies a file after the given toolId is run into target output directory.<copyFilename="destination"from="src"allowMissing="true"overwrite="true"toolId="filter"/>
magiclib - Internally used for replacing DLLs with object files.<magiclibname="libname"replace="old dll"/>
compiler - Defines a compiler. It is assumed only 1 compiler is active.
replace - when true the compiler is overridden, otherwise the contents of this node are appended to an existing compiler with the same id. (optional)exe - can be overridden in the body of the definition.<compilerid="id"exe="command"replace="true">...</compiler>
stripper - Defines a stripper, used to remove debug information for release from gcc executables.
replace - when true overwrites, otherwise appends. (optional)<stripperexe="command"replace="true">...</stripper>
linker - Defines a linker.
replace - when true overwrites, otherwise appends. (optional)id - can be static_link, dll, or exe. Usually all 3 linkers are defined.exe - can be overridden in the body of the definition.<linkerid="id"exe="command"replace="true">...</linker>
prelinker - Defines a prelinker.
replace - when true overwrites, otherwise appends.<prelinkername="id"replace="true"/>...</prelinker>
