# search for additional tools required for C/C++ (and other languages ?)
#
# If the internal cmake variable _CMAKE_TOOLCHAIN_PREFIX is set, this is used
# as prefix for the tools (e.g. arm-elf-gcc etc.)
# If the cmake variable _CMAKE_TOOLCHAIN_LOCATION is set, the compiler is
# searched only there. The other tools are at first searched there, then
# also in the default locations.
#
# Sets the following variables:
#   CMAKE_AR
#   CMAKE_RANLIB
#   CMAKE_LINKER
#   CMAKE_STRIP
#   CMAKE_INSTALL_NAME_TOOL

# on UNIX, cygwin and mingw
