CMake

  • Change the default for Trilinos_MUST_FIND_ALL_TPL_LIBS from OFF to
    ON. It was turned off by default because it breaks backward
    compatibility but it also causes problems for new users and new
    configurations.

    Users that do not want this new behavior can set
    -D Trilinos_MUST_FIND_ALL_TPL_LIBS=OFF, which is backward compatible.

  • Change the default for Trilinos_USE_GNUINSTALLDIRS from OFF to ON,
    in the goal to move Trilinos and TriBITS to modern CMake.

    TriBITS has had the ability to use that paths selected by the standard
    CMake module GNUInstallDirs.cmake for a long time. But it is turned off
    in TriBITS by default and was never turned on in Trilinos, both for the
    sake of backward compatibility.

    This may break people's existing configurations because it will install
    libs in <prefix>/libs64/ instead of in <prefix>/libs/ on many systems
    (e.g. Linux systems). For example, this will break downstream CMake
    projects that call find_package(Trilinos ...) before defining the
    compilers (e.g. so they can get the compilers from Trilinos). If the
    compilers are not defined, find_package() will not search
    <prefix>/lib64. To revert back to using <prefix>/lib but still use
    GNUInstallDirs.cmake for Trilinos, set -D CMAKE_INSTALL_LIBDIR:STRING=lib when configuring Trilinos. To avoid the
    find_package(Trilinos ...) problem not searching <prefix>/lib64,
    consider explicitly specifying the compiler to and having the downstream
    CMake project define the compilers first with project(<ProjectName> COMPILERS C CXX ...) before calling find_package(Trilinos ...). (That
    is, don't try to get the compilers from the installed Trilinos, see
    #12306.)

    NOTE: The setting -D Trilinos_USE_GNUINSTALLDIRS=OFF is deprecated and
    may be removed in the future. (I.e. the usage of GNUInstallDirs.cmake
    may be hard-coded in the future so please try adjusting to the usage of
    GNUInstallDirs.cmake by Trilinos.) See
    #12104 (comment)
    for additional details and instructions.
