# Typical usage:
# 0) install cmake version 2.8-9 or higher.
# 1) install a PizzaFactory cross compiler
# a) darwin toolchain targeting sh-elf: http://sourceforge.jp/projects/pf3gnuchains/downloads/50061/sh-pizzafactory-elf.pkg/
# b) install pkg.
# c) export PATH=$PATH:/pizza/bin
# 2) cp cmake/Toolchain-OSX-GenericShElf.cmake.sample ~/Toolchain-OSX-GenericShElf.cmake
# 3) tweak toolchain values as needed
# 4) cd build
# 5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-OSX-GenericShElf.cmake ..
# 6) Run mirb on gdb
# a) sh-pizzafactory-elf-gdb tools/mirb/mirb
# b) target sim
# c) load
# d) run
# name of the target OS on which the built artifacts will run
# and the toolchain prefix
set(CMAKE_SYSTEM_NAME Generic)
set(TOOLCHAIN_PREFIX sh-pizzafactory-elf)
# cross compilers to use for C and C++
set(CMAKE_C_COMPILER ${TOOLCHAIN_PREFIX}-gcc)
set(CMAKE_CXX_COMPILER ${TOOLCHAIN_PREFIX}-g++)
# target environment(s) on the build host system
# set 1st to dir with the cross compiler's C/C++ headers/libs
# set 2nd to dir containing personal cross development headers/libs
set(CMAKE_FIND_ROOT_PATH /pizza/${TOOLCHAIN_PREFIX})
# modify default behavior of FIND_XXX() commands to
# search for headers/libs in the target environment and
# search for programs in the build host environment
