[Help Needed] - Debugging compilation time

[ryuukk_]

I tried your project:

Linux x64

```
git clone https://github.com/MrcSnm/HipremeEngine.git
cd HipremeEngine
dub build (once to download dependencies if any)
time dub build -f


real	0m4.604s
user	0m3.686s
sys	0m0.900s
```

4.6 sec for a FULL rebuild doesn't seem that bad

and

```
real	0m1.730s
user	0m1.480s
sys	0m0.245s

```

after editing one module, not bad at all

As other people say:

LDC for release with optimizations
DMD for development

THat's what i personally do
