Installation of OGS 6.1 Data Explorer Error

[Eric Lappala]

I am trying to install the GUI for OGS 6.1 that is included in the latest source code from the GitHub

Using OS-X 10.13.6.  

Using any of:

 cmake with the -DOGS_USE_CONAN=ON AND -DOGS_BUILD_GUI=ON with or out using Xcode

 ccmake with the same arguments; or 

the OS-X make GUI.  

All works during the compile step until I get the following error:

CMake Error at scripts/cmake/SubmoduleSetup.cmake:34 (string):

   string sub-command REGEX, mode MATCH needs at least 5 arguments total to

   command.

 Call Stack (most recent call first):

   CMakeLists.txt:36 (include)

 CMake Error at scripts/cmake/SubmoduleSetup.cmake:35 (string):

   string sub-command REGEX, mode MATCH needs at least 5 arguments total to

   command.

 Call Stack (most recent call first):

   CMakeLists.txt:36 (include)

Here are lines 34 and 35 from the script needing the arguments:

    string(REGEX MATCH "^\\-" UNINITIALIZED ${SUBMODULE_STATE})

    string(REGEX MATCH "^\\+" MISMATCH ${SUBMODULE_STATE})

adding another \ to the things in the " " or a space does not fix this

All this only happens when trying to build the GUI - the CLI and all other modules compile and build fine

Thanks
