-# CMake build system for mruby
-# License: released under the same license as mruby
-# Author: jonforums@gmail.com
-# Author: beoran@gmail.com
-#
-# Usage example:
-#   1. Ensure CMake, Bison, and a build toolchain are on `PATH`
-#   2. Change to a build directory outside source tree, eg - `build` subdir
-#   3. Create build Makefiles or project files.
-#        `cmake ..`  (UNIX-like system)
-#        `cmake -G "MSYS Makefiles" ..`
-#        `cmake -G "Visual Studio 10" ..`
-#        `cmake -G "NMake Makefiles" ..`
-#      ** to cross-compile: add -DCMAKE_TOOLCHAIN_FILE=/path/to/toolchain/file
-#      ** to set install dir: add -DCMAKE_INSTALL_PREFIX=/path/to/installdir
-#  4a. Build: `make`  (to make noisy, add `VERBOSE=1`)
-#  4b. Build and test: `make all test`
-#  4c. Build, test, and install: `make all test install`
-#  4d. Build, test, and package: `make all test package`
