# Setup a build environment. This can take up to two parameters:
# argv[1] - build type, can be 'stable' or 'master'; anything else than
#           'stable' means 'master' build in the ./Makefile, which uses
#           relative path for build and if the respective folder is not
#           downloaded yet, then it creates a checkout from the master git
#           branch (hence the 'master' build name). There can be built
#           anything as master, the only condition is that the directory
#           with the sources is in place.
# argv[2] - use "debug" to build with debug options; using 'debug' build type
#           also uses debug build options
