cmake version 3.19 required?

[nigels-com]

I happened to be poking around with cmake builds and old versions of cmake in the context of nowide.

Parser builds for me on Ubuntu 24.04 with cmake-3.19.0, but not cmake-3.18.0.
And in CMakeLists.txt it's implied that 3.14 ought to work?

cmake_minimum_required(VERSION 3.14...3.20)

The problem concerns INTERFACE_LIBRARY

$ git clean -xdf . && PATH=/opt/cmake-3.18.0-Linux-x86_64/bin:$PATH cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTING=Y -DCMAKE_CXX_COMPILER=clang++-19 -DBOOST_INCLUDE_LIBRARIES=parser && ninja
...
CMake Error at libs/heap/CMakeLists.txt:22 (set_target_properties):
  INTERFACE_LIBRARY targets may only have whitelisted properties.  The
  property "CMAKE_CXX_STANDARD_REQUIRED" is not allowed.
...
CMake Error at libs/lockfree/CMakeLists.txt:45 (set_target_properties):
  INTERFACE_LIBRARY targets may only have whitelisted properties.  The
  property "CXX_STANDARD_REQUIRED" is not allowed.
...

So I do wonder if if boost can broadly agree on cmake-3.19.0 as a baseline that works, and we should collectively say that previous versions are simply not supported?

Should parse be requiring 3.19 rather than 3.14?

This is an issue of Boost.Heap and Boost.Lockfree not Boost.Parser. It is already fixed in the latter

Indeed. Resolved via boostorg/heap#55 and boostorg/lockfree#122

cmake-3.14.0 is working now for parser.
