CMake 2.8 was already deprecated some time ago, and newer CMake
versions, such as 3.22.1, would report its use as a warning.
CMake 3.13.5 is a reasonably stable version that is well supported among
most distributions and implements resonable policies, such as CMP0077:
https://cmake.org/cmake/help/latest/policy/CMP0077.html
However, bumping to 3.13.5 caused CMP0053 to now trigger configuration
errors on FindLibSndFile.cmake, as parentheses must now be escaped.
Further reference on CMP0053 can be found at:

Some additional minor changes were done the following files on the
migration from SVN to Git:
- mathexpr/CMakeLists.txt: commented code removed, make use of
target_include_directories().
- COPYRIGHT: since April 2024, mathexpr is MIT-licensed. The author made
