Configuration options

CMake options

Some of these options are enabled by default (“Defaults to ON”) otherwise they must be expicitly set to ON.

General

CMake switches to enable / disable parts of OGS.

• OGS_BUILD_CLI - Builds the simulator. Defaults to ON. If set to OFF all processes are also disabled.
• OGS_BUILD_GUI - Builds the Data Explorer. Defaults to OFF.
• BUILD_TESTING - Builds the test executables. Defaults to ON.
• OGS_BUILD_UTILS - Builds several utilities.
• OGS_NO_EXTERNAL_LIBS - Disables all external optional dependencies.
• OGS_BUILD_PROCESS_X - For enabling/disabling compilation of process X. Run the CMake-Gui to see a list of processes.
• OGS_BUILD_PROCESSES - A ;-separated list specifying processes to build. Defaults to an empty string. This will alter the OGS_BUILD_PROCESS_X-options. For e.g. building just the two processes HT and LIE: -DOGS_BUILD_PROCESSES="HT;LIE". Setting this variable back to an empty string does not reset the OGS_BUILD_PROCESS_X-options. You can also set it to OFF to disable all processes.

Debugging

• CMAKE_BUILD_TYPE - Defaults to Debug which builds with debugging infos, set to Release for an optimized build.
• OGS_PROFILE - Builds with profiling flags (-pg).
• OGS_CMAKE_DEBUG - Prints out the values of all defined CMake variables at CMake configuration time.

Optimization

• CMAKE_BUILD_TYPE - Set to Release to build with optimization flags, set to Debug for debugging.

Testing

• OGS_COVERAGE - Enables code coverage measurements with gcov/lcov. TODO

Advanced options

• OGS_CXX_FLAGS - Appends user-given compiler flags. Note that existing (CMake-given) flags are not replaced.
• OGS_ADDITIONAL_SUBMODULES_TO_CHECKOUT - Specifies optional submodules which are checked out at CMake-time. This is intended to be used by Jenkins.
• OGS_PACKAGE_ADDITIONAL_BINARIES - Package additional binaries (given as a ;-separated list with relative paths to CMAKE_BINARY_DIR) into redistributables. Is used for bundling the OGS File Converter with the Data Explorer.
• OGS_USE_OPTIONAL_SUBMODULES - Includes optional submodules into the build. The submodules have to be checked out before. Defaults to ON.
• OGS_CPU_ARCHITECTURE - Optimizes for the given CPU architecture see -march-flag. Defaults to native. For redistributable binaries set to generic on Linux and core2 on Mac OS.
• CMAKE_LIBRARY_SEARCH_PATH - Additional library installation path, e.g. /opt/local or C:/libs
