How to build smokeqt on Linux? 'windows.h' file not found

[hakonhagland]

After building smokegen as in #4, I am trying to build smokeqt on Ubuntu 21.10, clang version 11.0, Qt version 5.14.2:

$ git clone git@github.com:commonqt/smokeqt.git
$ cd smokeqt
$ mkdir build
$ cd build
$ cmake -DCMAKE_PREFIX_PATH="/opt/qt/qtbase/lib/cmake/Qt5;/usr/lib/llvm-11/lib/cmake/llvm;/opt/qt/smokegen/share/smoke/cmake" \
          -DCMAKE_C_COMPILER=clang-11 \
          -DCMAKE_CXX_COMPILER=clang++-11 ..

I think you want to conditionalise this to be Windows-only:
https://github.com/commonqt/smokegen/blob/8f88d3373258485b11e457da96240f5a6d82a5a9/generators/smoke/writeClasses.cpp#L82

@luismbo Thanks for the pointer! I tried to exclude line 82 in writeClasses.c on Linux, see this commit, and then recompiled smokegen on Linux with this change. When I now try to build smokeqt with this updated smokegen binary, I get and "Illegal instruction" error from make:
