cmake 3.14 is not enough

[paulduf]

Hello,

My laptop is running under Unbuntu 18.04. I tried first to build the software using first the stable system version of cmake (3.10) but I got an error managed on your own telling me that I must use cmake > 3.14. I updated cmake to 3.14.7 and tried again but stopped at the end of the process with an error related to the POP_BACK command, which may be available only in later versions of cmake (at least I see it available in 3.22, then I will try again with a more recent cmake version, but this should be documented and corrected anyway).

EDIT: I can confirm everything is fine with cmake 3.22.0

I give you the full output:

Thanks. Indeed the POP_BACK sub-command to format the display is not supported in CMake 3.14 but is available in 3.15 and up.

Another option is to replace line 145: list(POP_BACK CMAKE_MESSAGE_INDENT) replaced by list(REMOVE_ITEM CMAKE_MESSAGE_INDENT " ") which is supported by CMake 3.14
