ENH: merge CMake-CrossCompileBasic to HEAD -add a RESULT_VARIABLE to INCLUDE() -add CMAKE_TOOLCHAIN_FILE for specifiying your (potentially crosscompiling) toolchain -have TRY_RUN() complain if you try to use it in crosscompiling mode (which were compiled but cannot run on this system) -use CMAKE_EXECUTABLE_SUFFIX in TRY_RUN(), probably TRY_RUN won't be able to run the executables if they have a different suffix because they are probably crosscompiled, but nevertheless it should be able to find them -make several cmake variables presettable by the user: CMAKE_C/CXX_COMPILER, CMAKE_C/CXX_OUTPUT_EXTENSION, CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_INFO_FILE -support prefix for GNU toolchains (arm-elf-gcc, arm-elf-ar, arm-elf-strip etc.) -move ranlib on OSX from the file command to a command in executed in cmake_install.cmake -add support for stripping during install in cmake_install.cmake -split out cl.cmake from Windows-cl.cmake, first (very incomplete) step to support MS crosscompiling tools -remove stdio.h from the simple C program which checks if the compiler works, since this may not exist for some embedded platforms -create a new CMakeFindBinUtils.cmake which collects the search fro ar, ranlib, strip, ld, link, install_name_tool and other tools like these -add support for CMAKE_FIND_ROOT_PATH for all FIND_XXX commands, which is a list of directories which will be prepended to all search directories, right now as a cmake variable, turning it into a global cmake property may need some more work -remove cmTestTestHandler::TryExecutable(), it's unused -split cmFileCommand::HandleInstall() into slightly smaller functions Alex
