# This script is based in subsurface's packaging/windows/mxe-based-build.sh and
# works in the same fashion. Building needs to be done in a directory out of
# the source tree and, please, refer to said script for instructions on how to
# build.
#
# Subsurface *MUST* have been built before running that script, as the importer
# links against libsubsurface_corelib.a library.
# Although is possible to build the latest git version of the importer against
# whichever other version of subsurface, this should be avoided, and both
# versions, subsurface and smtk-import should be the same.
#
# Flags and options:
# -i (--installer): Packs a windows installer. This should always be used.
# -t (--tag):       Defines which git version we want to build. Defaults to
#                   latest. E.g. -t v4.6.4
# -b (--build):     Values: debug or release. Defines the build we want to do.
# -d (--dir):	    Specify a directory where a copy of the installer will be
#                   placed. This is a *must* if the script runs in a VM, and
#		    refers -usually- to a local dir mounted on the VM.
#
# Examples: (provided Subsurface has been previously cross built)
#
# smtk2ssrf-mxe-build.sh -i -t master
# This will build an release installer of smtk2ssrf placed in a directory under
# the win-build directory where it has been launched, named smtk-import. It will
# build git latest master regardless of subsurface's cross built version.
#
# smtk2ssrf-mxe-build.sh -b debug
# This will build *just* a windows binary (no packing) of the latest master.
#
# smtk2ssrf-mxe-build.sh -i -t v4.6.4 -b relase -d /mnt/data
# As I'm building in a fedora-25 docker VM, this should bring up a release
# installer of the v4.6.4 tag, and put a copy in my local mounted dir. In
# fact this *should* fail to build because of portability issues in v4.6.4.
