=> Besoin d'un comportement différent à partir de Boost 1.86 avec nouvelle syntaxe de process

Ongoing patch at https://github.com/Arthoni/openfluid/tree/updating-boost-process

• Working with archlinux
  Host :

docker build . -t ofbuild-archlinux:202505
runDocker /.../OF_Factory/ ofbuild-archlinux:202505

In docker :

cd /shared/development/openfluid/
mkdir _build_docker_archlinux
cd _build_docker_archlinux/
cmake ..  -DOFBUILD_ENABLE_DOCS=OFF  -DOFBUILD_ENABLE_GUI=OFF
make -j 16
ctest -j 15

• Not working with windows and mac OS : Boost process reading error in out stream: The pipe has been ended

Unable to replicate on local Msys2 (20250221), possibly because of boost version (1.87 in current downloadable msys2 version)
=> waiting for a new msys2 release including boost 1.88 to investigate further

Version 20250622 of msys2 may include Boost 1.88: https://packages.msys2.org/packages/?repo=mingw64

Requires deep check, eg real install on windows which would imply updating support package to boost 1.88, so postpone to when it will be necessary.
In current state, issues seem to remain, eg on GitUIProxy test (at least for MacOS).
