Compilation error when compiling IFC++ and TBB

Question

I am trying to compile IFC++ under linux

I tried following the instructions but it seems the project is currently broken under linux. To get the main library to compile I had to add:

find_package(TBB REQUIRED)
target_link_libraries(IfcPlusPlus PUBLIC TBB::tbb)

At the bottom of

IfcPlusPlus/CMakeLists.txt

This compiles and links. Then I tried compiling the example:

examples/SimpleViewerExampleQt

By running:

cmake -DIFCPP_SOURCE_DIR=../../ .. && make

This results in the following error:

In file included from /usr/include/oneapi/tbb/detail/_small_object_pool.h:23,

The source code throwing that error is perfectly fine so I think this is a bit of a red herring. What I don't know is what I might be doing wrong when compiling and/or setting up the cmake arguments. There's no documentation on how to get the example running so I am guessing.

As the comments suggest, it does seem the problem stems from the QT macro. I did try modifying the CMAKE file of the project by adding this line:

target_compile_definitions(SimpleViewerExampleQt PUBLIC QT_NO_KEYWORDS)

But I am getting a bunch of errors of this ilk instead:

/home/makogan/Foresight/ifcplusplus/examples/SimpleViewerExampleQt/build/src/moc_IfcPlusPlusSystem.cpp:208:5: error: no matching function for call to 'activate'
    QMetaObject::activate(this, &staticMetaObject, 4, nullptr);
    ^~~~~~~~~~~~~~~~~~~~~

So I think disabling the macro is not sufficient.
