building MoM tweaker on linux 64-bit, QT 4.8.5

[LoneVVolf]

After the success of building/ running the MoM customizer (see setup customization tool thread, page 5)
, i looked into building the tweaker also.

snapshot : momrtgt-code-b882e0fe8945b63fd60d300fe642152601e8f4c7.zip

extract file to ~/Temp/momrtgt-code-b882e0fe8945b63fd60d300fe642152601e8f4c7

Code:

$ cd ~/Temp/momrtgt-code-b882e0fe8945b63fd60d300fe642152601e8f4c7/Applications/MoMTweaker
$ qmake-qt4
$ make all
