Subject: [PATCH 1/2] Add libonly option to meson

    I wanted only library for djgpp.
    Compiler installed from rpm packages.

    Here is the build script:

    // mes.sh
    rm -rf /tmp/builddir_qjs

    PREFIX=/opt/qjs
    DESTDIR=$HOME/qjs

    LIBRARY_PATH="$PREFIX/lib" \
    PKG_CONFIG_PATH="$PREFIX/lib/pkgconfig" \
    C_INCLUDE_PATH="$PREFIX/include" \
    CFLAGS="-O2 -I$PREFIX/include" \
    CXXFLAGS="-O2 -I$PREFIX/include" \
    LDFLAGS="-L$PREFIX/lib" \
    meson setup /tmp/builddir_qjs --cross-file cross/linux-djgpp.ini \
    -Dprefix=$PREFIX \
    -Dexamples=disabled \
    -Dlibc=false \
    -Dtests=disabled \
    -Dlibonly=true || exit 1

    meson compile -C /tmp/builddir_qjs || exit 2

    mkdir -p $DESTDIR
    meson install -C /tmp/builddir_qjs --destdir $DESTDIR || exit 3

    // linux-djgpp.ini
    [binaries]
    c = ['/usr/bin/i586-pc-msdosdjgpp-gcc', '-Wno-incompatible-pointer-types']
    cpp = '/usr/bin/i586-pc-msdosdjgpp-g++'
    objc = '/usr/bin/i586-pc-msdosdjgpp-gcc'
    ar = '/usr/bin/i586-pc-msdosdjgpp-ar'
    pkg-config = '/usr/bin/pkg-config'
    strip = '/usr/bin/i586-pc-msdosdjgpp-strip'
    exe_wrapper = '/bin/true'
    ld = '/usr/bin/i586-pc-msdosdjgpp-ld'
    cmake = '/usr/bin/cmake'

    [properties]
    root = '/usr/i586-pc-msdosdjgpp'
    need_exe_wrapper = false

    [host_machine]
    system = 'dos'
    cpu_family = 'x86'
    cpu = 'i586'
    endian = 'little'

    [cmake]

    CMAKE_BUILD_WITH_INSTALL_RPATH     = 'ON'
    CMAKE_FIND_ROOT_PATH_MODE_PROGRAM  = 'NEVER'
    CMAKE_FIND_ROOT_PATH_MODE_LIBRARY  = 'ONLY'
    CMAKE_FIND_ROOT_PATH_MODE_INCLUDE  = 'ONLY'
    CMAKE_FIND_ROOT_PATH_MODE_PACKAGE  = 'ONLY'
