### C++ compiler (may be left blank - in this case, I guess which compiler
### to use from a list of options.
### If you must manually specify compiler, do so by naming it below.
CXX =

### Use a shell script to guess the compiler if not defined
ifeq ($(strip ${CXX}),)
CXX = $(shell ${SOURCEROOT}/makefiles/findcompiler.sh)
endif

### Target (debug or release)
### default is debug. The preferred way of specifying a target is to
### type "make TARGET=release" on the command line.
ifndef TARGET
TARGET = debug
endif

### Define the empty string
empty =

### Define operating system and CPU
OS =$(subst ${empty} ${empty},_,$(shell uname -s))
CPU =$(subst ${empty} ${empty},_,$(shell uname -m))

### The platform is determined by OS CPU and compiler 
PLATFORM = ${OS}_${CPU}_${CXX}

### Concatenation of platform and target yields a string used as 
### suffix of makefiles and in the name of the builddir.
PLATFORM_TARG = ${PLATFORM}_$(TARGET)
