Can't install kwin-lowlatency on Kubuntu 19.10

[Alexdegol]

I am unable to install kwin-lowlatency on Kubuntu 19.10. I followed these steps:

$ wget https://download.kde.org/stable/plasma/5.17.0/kwin-5.17.0.tar.xz $ wget http://tildearrow.zapto.org/storage/kwin-lowlatency/kwin-lowlatency-5.17.0.patch EXTRACT $ tar -xvf kwin-5.17.0.tar.xz PATCH: $ cd kwin-5.17.0 $ patch -p1 < ../kwin-lowlatency-5.17.0.patch

BUILDING $ mkdir build $ cd build $ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib/x86_64-linux-gnu -DCMAKE_INSTALL_LIBEXECDIR=lib/x86_64-linux-gnu -DBUILD_TESTING=OFF $ make

When I run "cmake -DCMAKE [etc.]" the terminal prompts this message:

CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases.

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake:28 (find_package): Could not find a package configuration file provided by "Qt5Quick" with any of the following names:

Qt5QuickConfig.cmake
qt5quick-config.cmake

Add the installation prefix of "Qt5Quick" to CMAKE_PREFIX_PATH or set "Qt5Quick_DIR" to a directory containing one of the above files. If "Qt5Quick" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): CMakeLists.txt:21 (find_package)

Now I get this:

CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases.

Build the entire kwin-lowlatency source code in Launchpad instead of trying to patch it locally. I'm also perfectly happy to accept Kubuntu build support in my OBS repository (linked in ReadMe file).

I think you're missing the .. at the end of the cmake command line. Manual compilation instructions were very recently updated to add this, see https://github.com/tildearrow/kwin-lowlatency/commit/d634bc01ed691a89c524ec2c907ab25c818cecbd.

It's been a while. @Alexdegol did you read @maxiberta's comment?

Closing due to lack of response.
