# This is the top-level CMakeLists.txt file for the Cuberite project
#
# Use CMake to generate the build files for your platform
#
# This script supports some configuration through CMake arguments (-Dparam=val syntax):
# BUILD_TOOLS=1 sets up additional executables to be built along with the server (ProtoProxy, GrownBiomeGenVisualiser, MCADefrag)
# BUILD_UNSTABLE_TOOLS=1 sets up yet more executables to be built, these can be broken and generally are obsolete (GeneratorPerformanceTest)
# NO_NATIVE_OPTIMIZATION=1 disables CPU-specific optimisations for the current machine, allows use on other CPUs of the same platform
# DISABLE_SYSTEM_LUA=1 disables the use of system Lua interpreter; the tolua executable will be built and used instead. Incompatible with cross-compiling
# SELF_TEST=1 enables testing code to be built
