Subject: [PATCH] pahole: Set `LIB_INSTALL_DIR` to fix lib install directory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, [the shared libraries are wrongly installed into
`/usr/usr/lib`][1]:

    $ pahole --version
    pahole: error while loading shared libraries: libdwarves_emit.so.1: cannot open shared object file: No such file or directory
    $ fakeroot bee query pahole-1.30-0.x86_64

    /usr/usr/lib/libdwarves_reorganize.so.1//libdwarves_reorganize.so.1.0.0
    /usr/usr/lib/libdwarves_reorganize.so.1.0.0
    /usr/usr/lib/libdwarves_emit.so//libdwarves_emit.so.1

    /usr/usr/lib/libdwarves.so//libdwarves.so.1
    /usr/usr/lib/libdwarves.so.1//libdwarves.so.1.0.0
    /usr/usr/lib/libdwarves.so.1.0.0
    […]

The problem is, that `CMAKE_INSTALL_LIBDIR` is treated to be
subdirectory of the install prefix and *not* an absolute path:

    $ more CMakeLists.txt
    […]
    if (NOT DEFINED LIB_INSTALL_DIR)
        set(LIB_INSTALL_DIR "${EXEC_INSTALL_PREFIX}${CMAKE_INSTALL_PREFIX}/${CMAKE_INSTALL_LIBDIR}")
    endif()
    […]

Explicity set `LIB_INSTALL_DIR` to make the if condition false.

    v1.30
