# CMakeLists.txt - CMake configuration file for EPANET 2.0
#
# CMake is a cross-platform build tool. CMake generates platform native
# build systems that can be used with your compiler of choice. CMake uses a
# generator concept to represent different build tooling. CMake automatically
# detects the platform it is running on and generates the appropriate makefiles
# for the platform default compiler. Different generators can also be specified.
#
# Note: CMake requires that your platform build system and compiler are
# properly installed. Build using Visual Studio requires msbuild shell.
#
# Build Options:
#   BUILD_TESTS = ON/OFF
#   BUILD_PY_LIB = ON/OFF
#
# Generic Invocation:
#   cmake -E make_directory buildprod
#   cd build
#   cmake -G GENERATOR -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTS=ON ..
#   cmake --build . --target SOME_TARGET --config Release
#
# More information:
#   cmake --help
#
#   CMake is available at https://cmake.org/download/
#
