My first attempt at building Sigil 2.0.2 with Qt6 has failed at the configuration stage. I tried to use the system libraries for hunspell, pcre2, minizip. The consol command I used was :

cmake -G "Unix Makefiles" -DUSE_SYSTEM_LIBS=1 -DCMAKE_BUILD_TYPE=Release ../sigil-src

The libhunspell-dev, libpcre2-dev, libminizip-dev packages are installed on my system.

The consol output shows that ZLIB and MiniZip were found but no mention of hunspell or pcre2. A few lines further down, it indicates cmake was using bundled Hunspell and PCRE2. This, I suppose is not so serious as what follows.

Next failure was: windows.h not found and the CMakeError.log shows that as a fatal error.

A few more lines down, the consol output shows:

 Looking for C++ include type_traits.h
-- Looking for C++ include type_traits.h - not found
-- Looking for C++ include bits/type_traits.h
-- Looking for C++ include bits/type_traits.h - not found

Again, the CMakeError.log shows these as fatal errors.

Further down, I find:

Looking for _strtoi64 - not found

this is referred to in CMakeError.log as "undefined reference to `_strtoi64'"

Then the consol output turns red :

The imported target "Qt6::qwebengine_convert_dict" references the file
     "/usr/lib/qt6/libexec/qwebengine_convert_dict"
  but this file does not exist.

and further:

and then in orange color:

  Found package configuration file:
    /usr/lib/x86_64-linux-gnu/cmake/Qt6WebEngineCore/Qt6WebEngineCoreConfig.cmake

  but it set Qt6WebEngineCore_FOUND to FALSE so package "Qt6WebEngineCore" is
  considered to be NOT FOUND.

I guess this last bit about Qt6WebEngineCore says something about the naming conventions. I do have qt6-webengine-dev installed.
