Please forgive me for posting this again, but I think it would be better to have it in Matrix logs too:

Would you mind to create and change the directory first?
```
%build
mkdir build
cd build
cmake \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=%{_prefix} \
  -DCMAKE_INSTALL_LIBDIR=%{_libdir} \
  -DCMAKE_VERBOSE_MAKEFILE=ON \
  ..
cmake --build .

%install
cd build
rm -rf %{buildroot}
DESTDIR=$RPM_BUILD_ROOT cmake --build . --target install
```


This works for me in my telegram-qt build.

Check my telegram-qt spec and build status here:
https://build.merproject.org/package/show/c:telepathy:devel:morse/telegram-qt

(I wrote the spec time ago and I would do it different nowadays, but the thing is that special build directory works in this sample.)
