 - `OGS_BUILD_GUI` - Builds the Data Explorer. *Defaults* to *OFF*.
 - `OGS_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.
