      -DCMAKE_BUILD_TYPE=Release         \
      -DBUILD_TESTING=OFF                \

make install

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.
