[yocto] Using the SDK and CMAKE GNUInstallDirs for multilib target

[Måns Zigher]

Hi,

I found in cmake.bbclass

cmake \
      ${OECMAKE_GENERATOR_ARGS} \
      $oecmake_sitefile \
      ${OECMAKE_SOURCEPATH} \
      -DCMAKE_INSTALL_PREFIX:PATH=${prefix} \
      -DCMAKE_INSTALL_BINDIR:PATH=${@os.path.relpath(d.getVar('bindir'),
d.getVar('prefix'))} \
      -DCMAKE_INSTALL_SBINDIR:PATH=${@os.path.relpath(d.getVar('sbindir'),
d.getVar('prefix'))} \
      -DCMAKE_INSTALL_LIBEXECDIR:PATH=${@os.path.relpath(d.getVar('libexecdir'),
d.getVar('prefix'))} \
      -DCMAKE_INSTALL_SYSCONFDIR:PATH=${sysconfdir} \
      -DCMAKE_INSTALL_SHAREDSTATEDIR:PATH=${@os.path.relpath(d.getVar('sharedstatedir'),
d.  getVar('prefix'))} \
      -DCMAKE_INSTALL_LOCALSTATEDIR:PATH=${localstatedir} \
      -DCMAKE_INSTALL_LIBDIR:PATH=${@os.path.relpath(d.getVar('libdir'),
d.getVar('prefix'))} \
      -DCMAKE_INSTALL_INCLUDEDIR:PATH=${@os.path.relpath(d.getVar('includedir'),
d.getVar('prefix'))} \
      -DCMAKE_INSTALL_DATAROOTDIR:PATH=${@os.path.relpath(d.getVar('datadir'),
d.getVar('prefix'))} \
      -DCMAKE_INSTALL_SO_NO_EXE=0 \
      -DCMAKE_TOOLCHAIN_FILE=${WORKDIR}/toolchain.cmake \
      -DCMAKE_NO_SYSTEM_FROM_IMPORTED=1 \
      ${EXTRA_OECMAKE} \
      -Wno-dev

so it looks all CMAKE_INSTALL paths are actually managed by cmake class.
