[Bug]: `unset [name]; export [name]=value; source rvcmds.sh` has no effect

[michimussato]

What happened?

rvcmds.sh does not behave as expected.

# source /rv_git/OpenRV/rvcmds.sh 
RV_VFX_PLATFORM already set to CY2024.
Using Qt 6.5 installation already set at /opt/Qt/6.5.3/gcc_64
Please ensure you have installed any required dependencies from doc/build_system/config_[os]

CMake parameters:
RV_BUILD_PARALLELISM is 8
RV_HOME is /rv_git/OpenRV
RV_BUILD_DIR is /rv_git/OpenRV/_build
RV_INST_DIR is /rv_git/OpenRV/_install
CMAKE_GENERATOR is Ninja
QT_HOME is /opt/Qt/6.5.3/gcc_64

To override any of them do unset [name]; export [name]=value; source /rv_git/OpenRV/rvcmds.sh

Use 'rvrelease' (default) or 'rvdebug' to switch between build configurations.
Call 'rvbootstrap' if its your first time building or after calling rvclean.
After 'rvbootstrap', use 'rvbuild' or 'rvmk' for incremental builds.

If build fails, use 'rverrsummary' to see error summary or 'rverrors' to view full log.

Ok, To override any of them do unset [name]; export [name]=value; source /rv_git/OpenRV/rvcmds.sh:
