Stuck on splash screen, compiling twice fixes this

[memtech3]

When compiling the first time headunit-desktop sometimes gets stuck on the splash screen. Running

protoc --proto_path=modules/android-auto/headunit/hu/ --cpp_out=modules/android-auto/headunit/hu/generated.x64/ modules/android-auto/headunit/hu/hu.proto modules/android-auto/headunit/hu/bt.proto
mkdir build && cd build
qmake PREFIX=~/hud ../headunit-desktop.pro
make -j5
make install

again fixes this
