MIQT Compile benchmarks game

[mappu]

The first time you use MIQT, it must be compiled. The first build can be slow, but after this, any go build takes only a few seconds.

To assist #8 it would be good to collect numbers from different people about how fast MIQT's first compilation is. Please include CPU, Go version, and MIQT Git tag.

Notes:

• In Go 1.24, CGO compilation will become more multi-threaded. Prior to this, it's single-threaded
• Qt5 seems to build faster than Qt6
• The system default CGO_CXXFLAGS are -g -O2. Would different CFLAGS (e.g. -O0) be interesting?
