Fix Mem-leak and CMake issues

[Snapex2409]

• Fixes a mem-leak encountered during Reader::ReadMS
• Updates CMake files to support a wider range of systems. Depending on the system, the previous version would sometimes fail to compile.

Checklist:

• I made sure that the CI passed before I ask for a review.
• I added a summary of the changes (compared to the last release) in the CHANGELOG.md.
• If necessary, I made changes to the documentation and/or added new content.
• I will remember to squash-and-merge, providing a useful summary of the changes of this PR.
