1. xf86-video-intel

The lastest source codes can be found from: 
https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel

I used the following instructions to build the codes (please note that you can 
find more options from meson_option.txt):

mkdir -p build
cd       build

meson --prefix=$XORG_PREFIX \
      --sysconfdir=/etc     \
      --localstatedir=/var  \
      -Dums=FALSE           \
      -Dvalgrind=FALSE      \
      ..
ninja
ninja install

I could start KDE Plasma 5.13.4 with this driver for a computer that uses Intel 
Atom E3825.

2. Qt 5.11

If you will copy the generated Qt5 from the native system to a less capable 
system (in my case, from Intel I5 4570 to Intel Atom E3825), you have to add 
additional options in order to disable the unsupported instruction sets. 
Otherwise the Qt applications such as KDE Plasma will crash. For example, I 
have to disable SSE4.1, SSE4.2 and AVX instruction sets for Atom E3825:

./configure -prefix $QT5PREFIX                          \
            -sysconfdir /etc/xdg                        \
            -confirm-license                            \
            -opensource                                 \
            -dbus-linked                                \
            -openssl-linked                             \
            -system-harfbuzz                            \
            -system-sqlite                              \
            -nomake examples                            \
            -no-rpath                                   \
            --sse4.1=no                                 \
            --sse4.2=no                                 \
            -skip qtwebengine

3. LibZip

It is an optional package for KDE Ark.

The lastest source codes (version 1.5.1) can be found from: 
https://libzip.org/download/

It is my build instructions:

mkdir build &&
cd    build &&

cmake -DCMAKE_INSTALL_PREFIX=/usr \
      -DCMAKE_BUILD_TYPE=RELEASE  \
      .. &&
make
make install
