building on a Mac

[Guido Lerch]

Hi Dirk,

Thanks for all your efforts.
I though it might be useful to protocol on how I uninstalled what you listed below.

What is kind of frustrating is that when removing QT with the maintenance tool, which is what they recommend, certain traces in the /usr/local/ folder remain
from which a normal user would not know what can be deleted vs. what not.

For example: /usr/local/lib contains
/cmake/ : assume can be removed
libosxfuse_xxx
tons of libQT5xxxx and QTxxx  stuff
/pkgconfig/ : can go

/usr/local/libexec contains QTWebProcess

/use/local/qml contains lots of QTxxxx stuff
 
There is more and I am not 100% sure what to remove and what not, if I keep it there, would that have any negative impact ?

Uninstalling:

1. ) ran
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
to uninstall brew

2.) ran maintenance tool to “remove” QT

3.) removed the entire ~/src folder and recreated it

I’ll wait for feedback till I continue with the installation

Viele Güsse, Best regards,

Guido Lerch
