Installation of libkscreen

Install libkscreen by running the following commands:

mkdir -v build &&
cd       build &&

cmake -DCMAKE_INSTALL_PREFIX=/usr        \
      -DCMAKE_BUILD_TYPE=Release         \
      -DCMAKE_INSTALL_LIBEXECDIR=libexec \
      -DKDE_INSTALL_USE_QT_SYS_PATHS=ON  \
      -DBUILD_TESTING=OFF                \
      -Wno-dev ..                        &&
make

This package does not come with a test suite.

Now, as the root user:

make install

Next, remove a systemd unit which serves no purpose on a SysV system as the root user:

rm -v /usr/lib/systemd/user/plasma-kscreen.service

Command Explanations

-DCMAKE_INSTALL_LIBEXECDIR=libexec: This overrides the default in extra-cmake-modules, which is /usr/lib/libexec and is not FHS compliant.

-DKDE_INSTALL_USE_QT_SYS_PATHS=ON: This forces installation of Qt plugins in the same directory as Qt-5.15.12 itself. Otherwise they get installed into /usr/mkspecs, which is not FHS compliant.
