[Lazarus] Got Lazarus 2.0.0 from SVN, missing help files

[Bo Berglund]

I installed Lazarus 2.0.0 on Linux Mint 19 using svn to check out tag
2_0_0 and doing a make bigide inside.

It all worked well to get Lazarus up and running, but now I found a
problem regarding help...
When I want to check the syntax for a command using the F1 key there
is a dialog saying it cannot find rtl.chm.

What can I do to rectify this?
find does not find any such file on my system...
