REG[4.8-5.6] QMake generated xcodeproj doesn't support Time Machine backup

Generate .xcodeproject. Build with Xcode. See that whole application directory will be excluded from the Time Machine.

Comparing to Qt 4.8.7 this doesn't happen. Difference is that Qt 4 creates build subdirectory for build files. But Qt5 creates build files to the application directory.

Qt 4.8:
Check that "timemachine" application folder is not excluded:

sudo mdfind "com_apple_backup_excludeItem = 'com.apple.backupd'" | grep "timemachinetest"

Create Qt 4.8 xcodeproj file:

/work/qt/installer/4.8/cocoa_gcc/bin/qmake -spec macx-xcode

Build Xcode project:

xcodebuild -target timemachitetest

Check excluded application directories:

sudo mdfind "com_apple_backup_excludeItem = 'com.apple.backupd'" | grep "timemachinetest"
/work/timemachinetest/build/timemachinetest.build
/work/timemachinetest/build

Notice that both excluded directories are generated build directories
Delete generated files:

rm -fr build Info.plist timemachinetest.xcodeproj moc_mainwindow.cpp ui_mainwindow.h 

Qt5:
Check that "timemachine" application folder is not excluded:

sudo mdfind "com_apple_backup_excludeItem = 'com.apple.backupd'" | grep "timemachinetest"

Create Qt 5.6 xcodeproj file:

/work/qt/installer/5.6/clang_64/bin/qmake -spec macx-xcode
xcodebuild -target timemachinetest

Check excluded application directories:

sudo mdfind "com_apple_backup_excludeItem = 'com.apple.backupd'" | grep "timemachinetest"
/work/timemachinetest

Notice that Application directory is excluded and won't be backup from Time Machine.
Delete generated files:

rm -fr Info.plist moc_mainwindow.cpp ui_mainwindow.h Release timemachinetest.build timemachinetest.xcodeproj

User have to remove exclusion manually if application directory is wanted to be backed up by Time Machine

tmutil removeexclusion /work/timemachinetest

So problem seems to be that timemachinetest.build is generated to the application directory and Xcode will exclude that directory. Qt4 it's located in "build"-subdirectory and won't cause the issue.
