Qt5.15.5 on Lubuntu 18.04 32-bit

Hello!
I have compiled Qt5.15.5 on Lubuntu 18.04, 32-bit. GLIBC 2.27.
It was a bit cumbersome, so if anyone intends to do something similar, I will share my experiences.

Configure options:

../qt-everywhere-src-5.15.5/configure -release -prefix "/opt/Qt/Qt5.15.5" -opensource -confirm-license -silent -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -system-freetype -opengl desktop -make libs -nomake examples -nomake tests -skip qtwayland -skip qtwebview -skip qtwebengine -skip qtwebchannel -nomake tools -flite

make
//worked as it should

sudo make install 
//as the worries began

First error messages, more would follow

/usr/bin/ld: cannot find -lclip2tri
/usr/bin/ld: cannot find -lpoly2tri
/usr/bin/ld: cannot find -lclipper

sudo apt install asound-dev*
sudo apt install flite-dev*

// cd to each directory and do 'sudo make' to each of them:
cd ~/build/qtlocation/src/3rdparty/clip2tri
cd ~/build/qtlocation/src/3rdparty/clipper
cd ~/build/qtlocation/src/3rdparty/poly2tri
cd ~/build/qtlocation/src/plugins/geoservices
cd ~/build/qtvirtualkeyboard/src/plugins/openwnn/3rdparty/openwnn
cd ~/build/qtvirtualkeyboard/src/plugins

After this it worked!

Thank you for sharing. I will have a spin on it as well.
