Build script improvements. (#7914)

* Build script improvements.

Add NDEBUG for non-debug MacOS builds. I don't understand why, but on my system Release and RelWithDebugInfo builds were not defining NDEBUG, resulting in failing asserts and other sanity checks.

Add -jN flag to BuildLinux.sh. On my 4-core 8GB RAM system, passing -j4 allows building without a swap storm.

Improve README.md description of building on macOS.

* Merge branch 'main' into bug/macos-ndebug

* Merge branch 'main' into bug/macos-ndebug

* Merge branch 'SoftFever:main' into bug/macos-ndebug

* Improve CMake syntax. Mention Mac path to app.

* Merge branch 'main' into bug/macos-ndebug
