Building OpenJFX on clean install of CentOS 8

[Michael Franz]

Hi,

Just to report that I was able to get OpenJFX development setup on CentOS 8
using the following steps:
0. sudo yum update
1. sudo yum install git bison flex pkgconfig gtk2-devel gtk3-devel
pango-devel freetype-devel libXtst-devel java-11-openjdk-devel ant gcc-c++
2. sudo yum install epel-release
3. sudo yum config-manager --set-enabled PowerTools
4. sudo yum update
5. sudo yum install libstdc++-static
6. sudo alternatives --config java
- specify Java 11

There are more steps than CentOS 7, however CentOS 8 has gcc 8.2.1 so there
is not need to manually install.

Now that my two development platforms are setup, I hope to start
contributing.

Michael
