Custom build fails: what is wrong in my settings?

[ccoustet]

I am trying to build the 7.9.1 release from sources on a quite old system (Debian Buster):

gcc (Debian 8.3.0-6) 8.3.0
cmake version 3.13.4

The flags I provide to cmake are:

cmake .. \                                                                 
     -DCMAKE_BUILD_TYPE=RELEASE \                                                 
     -DBUILD_MODULE_ApplicationFramework=0 \                                      
     -DBUILD_MODULE_DETools=0 \                                                   
     -DBUILD_MODULE_Draw=0 \                                                      
     -DBUILD_MODULE_Visualization=0 \                                             
     -DBUILD_LIBRARY_TYPE=Static \                                                
     -DUSE_FREETYPE=0 \                                                           
     -DUSE_OPENGL=0 \                                                             
     -DUSE_TK=0 \                                                                 
     -DUSE_XLIB=0 \
     -DINSTALL_DIR=local 

The error occurs at a very early stage:

What am I doing wrong?
Thanks.

That error is problem with cmake-3.13 version. (removing duplicates have another signature)
Please move to the more modern version. You can build it manually or download from KitWare.
_
Original issue: some version of CMake requires REMOVE_DUPLICATES and REMOVE_ITEM to have at least one symbol on it, but sometimes we can have just empty string.

[ccoustet]

I will try to install an up to date version if it can link against the old Buster libc. Otherwise I will have to build from sources or try to patch your cmake scripts.
May be should you set the required cmake version number accordingly?

[dpasukhi]

I'm planning to fix that issue. But it will be not in 7.9.2.
It is trivial fix, need to add if/endif blocks to check empty variables.
No needs to up-to-date version, you can use 3.15.

Also you can use portable version of CMake and build only OCCT with modern versions, your project can be build with stable.
I'm not expecting issues with 3rd-party for OCCT related to CMake

[ccoustet]

Building cmake 3.31 from source fixed the issue.
It needed adding an arg at the bootstrap stage, though:
./bootstrap -- -DCMAKE_USE_OPENSSL=OFF
