## Change binary & resources folder to parallel install with original GD.
## This flag should be avoided because it leads to small regressions:
## 1. There are personal scripts assuming the binary name to be "goldendict" -> require everyone to change the name in their script
## 2. There are icon themes that assuming the icon name to be "goldendict" -> invalidate the GD icon when using a icon theme
## 3. There are dictionary packages that install files to "/usr/share/goldendict/content" -> nullify the auto dict discovery
