# If need to set debug options
#   1.Generate debug version:
#     mkdir debug; cd debug;
#     cmake -DCMAKE_BUILD_TYPE=Debug ..
#   2.Generate release version:
#     mkdir release; cd release;
#     cmake -DCMAKE_BUILD_TYPE=Release ..
#

#
# If it is a Windows operating system
#   1.Use command line tool of VS2013 or higher version
#     mkdir build; cd build;
#     cmake -G "NMake Makefiles" ..
#     nmake install
#   2.Use the VS development interface tool
#     mkdir build; cd build;
#     cmake -A x64 ..
#     open the file named TDengine.sln
