### MODE:          release|debug determines what compiler flags to use
### ARCH:          32|64 determines 32- or 64-bit build. If not specified, system default is used
### SYSTEM:        mingw|linux|cygwin determines the compilation environment. Autodetect if not specified
### DEFINES:       list of predefined macros to pass to the compiler
### INC_DIRS:      list of include paths to pass to the compiler
### DEP_INC_DIRS:  list of include paths to search for dependencies in
### LIB_DIRS:      list of library paths to pass to the linker
### TARGET_TYPE:   determines whether to build executables or libraries
### SOURCES:       list of source (c++) files
### SRC_DIRS:      list of source paths. Needed to generate implicit rules
### SOURCE_LIBS:   list of locally built libs (they are included as a dependency)
### LINK_LIBS:     list of libraries to link againsg on top of SOURCE_LIBS
### TARGETS:       list of target final targets (library names or executable files)
### SIM_BASE:      location for the simulation sources. Defaults to ..

### CPATH:         make sure boost is in the search path. If not, adjust this environment variable so that it is
### LIBRARY_PATH:  make sure boost libraries are in the search path. If not, adjust this environment variable so that they are
