Bugs in LibPack 12.5.3

[donovaly]

many thanks for you new Libpack. We wanted to release FreeCAD 0.19.3 and while doing so I found these issues:

• at first a question: does the LibPack still contain the fixes for OCC from @chennes ? Or how can I find this out?

• I get his compilation error:
  LINK : fatal error LNK1181: cannot open input file 'C:\Strawberry\c\lib\libfreetype.a' 2>Done building project "Driver.vcxproj" -- FAILED.
  The link to freetype needs to be changed to "freetype.lib" here are the 2 fixed CMake files.
  LibPack-CMake-fixes.zip

When you are maybe fixing the freetype issue, would it be possible to upgrade to OCC 7.5.3 and keep @chennes OCC fixes in? These OCC fixes are these: https://github.com/msys2/MINGW-packages/tree/master/mingw-w64-opencascade

(Just for the record, only one of those patches is mine, most of the rest are from blobfish/tanderson).

from the 10 commits number 0002 to 0008 are from you ;-)

Meanwhile it seems that the LibPack contains your fixes. Is this right @apeltauer ? Then all that has to be done is to apply the fixed CMake files I attached in my initial post.

@apeltauer I just realized that you use Qt 5.15.1. During the release of FC 0.19.2 we found out that we must use Qt 5.15.2 to overcome some bugs fixed there. Can you please update your LibPack to this Qt version?

To keep the overview, I opened now different reports for the different issues.

Closing this one in favor of #14, #15. #16, #17, #18 and #19
