Bitcoin 0.18 / Ubuntu 0.18.2 Trying to cross compile on Linux for Windows.

When I execute configure everything is fine except for QT
```
checking QtPlugin usability... no
checking QtPlugin presence... no
checking for QtPlugin... no
configure: WARNING: QtCore headers missing; bitcoin-qt frontend will not be built
```
The wallet cannot be compiled because of missing QT5. I have installed QT5 in many different ways, I have qmake in the path.

Is there anyone else with this problem? Is there a way to fix it?

I have found the problem. Depending on the Linux install you chose, you may have QT5 and QT4 already installed

Doing
```
sudo apt autoremove '.*qt5.*-dev'
sudo apt autoremove '.*qt4.*-dev'
```
then install the depends fixes the problem
