Question about docker build environment: CMake version for docker build seems to be different than my installed version. Environment variable? about isaac_ros_base

I ended up adding this into 'Dockerfile.isaac' script to fix the issue.

#Install required dependencies
RUN apt-get update && apt-get install --reinstall distro-info
RUN apt install apt-utils

bug fix associated with 'Invalid Version '0.23ubuntu1' (6/26/2023)

RUN pip install --upgrade --user setuptools==58.3.0

Set the CMake version

ENV CMAKE_VERSION 3.26.4

Download and install specific CMake version

RUN wget "https://cmake.org/files/v${CMAKE_VERSION%.*}/cmake-${CMAKE_VERSION}.tar.gz" &&
tar -xzvf "cmake-${CMAKE_VERSION}.tar.gz" &&
cd "cmake-${CMAKE_VERSION}" &&
./bootstrap &&
make &&
make install

#Remove /usr/bin/cmake
RUN rm -f /usr/bin/cmake

Set the default CMake version

RUN ln -s /usr/local/bin/cmake /usr/bin/cmake

Here is a quick update: even after I updated to cmake 3.26.4, when running in isaac_ros_base/example directory:

docker build -t isaac-ros-base/packages:latest -f Dockerfile.isaac .

It still throws the error:

Starting >>> isaac_ros_common
Starting >>> isaac_ros_test
--- stderr: isaac_ros_common
CMake Error at CMakeLists.txt:9 (cmake_minimum_required):
CMake 3.23.2 or higher is required. You are running version 3.16.3

---

Failed <<< isaac_ros_common [0.64s, exited with code 1]

I did look in CMakeLists.txt and it is requiring a version later than CMake3.23.2.
However I do not understand why docker build still seems to have 3.16.3 in the shell environment, when I did update to 3.26.4

Thanks again for your help!
