Trouble building Gnucash on 10.1 systemd

Hi Everyone,

I get an error building gwenhywfar-4.20.0 needed for Gnucash.

checking for qt4 includes... not found
checking for qt4 libraries... not found
checking for qt4 moc... not found
checking for qt4 uic... not found

configure: error:
Compilation of QT applications is enabled but I could not find some Qt
components (see which are missing in messages above).
If you don't want to compile Qt4 applications please explicitly specify
which GUIs you want to support using "--with-guis".

I have tried several --with-guis" to no success. with ./configure --prefix=/usr

Thanks for any help and pointers

Have a great day
