CMake command FetchContent_MakeAvailable introduced in CMake version 3.14?

[hakonanes]

Building EMsoft 5.0 with cmake version 3.12.1 I get

> cmake --version
cmake version 3.12.1
> cmake -DCMAKE_BUILD_TYPE=Release -DEMsoft_SDK=/home/hakonwii/emsoft/EMsoft_SDK -DEMsoft_ENABLE_EMsoftWorkbench=OFF /home/hakonwii/emsoft/EMsoft

The release notes for cmake version 3.14 (https://cmake.org/cmake/help/v3.14/release/3.14.html#modules) mentions this command as new in that version... Should cmake_minimum_required be adjusted to 3.14?

After reverting to the commit before the use of the CMake command was introduced (d8bea98a0bbb5667e4590f84fd9c89614e212fff), I'm now told that to build the SHTfile project I need CMake 3.14.

Yes, you are correct; you should use 3.14.5 or more recent... I have updated this on the Superbuild and EMsoft repositories.

Great, thanks.
