mkdir: cannot create directory ‘Build’: File exists
If it is the first time installation:
if [ ! -d "$myRepo/opencv" ]; then
....
mkdir Build
...
and
if [ ! -d "$myRepo/opencv_contrib" ]; then
...
mkdir Build
...
Both try to create the Build/
The second attempt fails and halts the script. Should create the dir only if it does not exists.
