OK, that is a Lazarus global option.
If I want to build using 3.0.4 rather than 3.2.0 I will set this option
correspondingly, right?
But then if I forget about it and close Lazarus after the build and then later
come back and need to rebuild Lazarus, what will happen?
Will it try to use 3.0.4 in this case and fail since 3.2.0 is the minimum for
building Lazarus 2.0.10?

Or should I set the global option to 3.2.0 and if I want to build a *project*
then use the selector below Project/Project Options?
In Project Options/Compiler Options/Compiler Commands there is a drop-down for
selecting the specific compiler.

I assume if this is left as is as $(CompPath) it will use the globally defined
compiler 3.2.0, but if changed will use the project defined compiler instead.
