The AMD64 ABI document http://www.x86-64.org/documentation/abi.pdf
does specify that 64bits binary libraries should end up in <prefix>/lib64
and 32bits ones in <prefix>/lib. All but debian based distros do so,
and some like OpenSUSE even enforce the rule when packaging with RPM
and refuse to build the RPM if this is not the case.
After some discussion (see the bug notes) we cannot do that behind
the scene and the current fix supposes that the user shall use
the CMAKE_INSTALL_LIBDIR variables content in its INSTALL rules if
he wants to put the lib in the right place. CMAKE_INSTALL_LIBDIR
shall have the appropriate value depending on the Linux distribution
found and 32/64bitness of the host.
The cross-compiling case (even 32bits compile on a 64bits host)
is not handled.
Also allow generators to override the default packaging method.
Add a ONE_PER_GROUP option so that method can be specified by the user without relying on defaults.
All commands accepting file paths should normalize the slashes so that
the string-represented names can be compared reliably. The commands
add_library and add_executable have done this for years. We taught
add_custom_command to normalize its OUTPUT names in commit a75a0a14
(Normalize add_custom_command OUTPUT names, 2010-12-15). We handled a
special case of the DEPENDS option in commit 7befc007 (Handle trailing
slashes on add_custom_command DEPENDS, 2011-01-26).
Teach both add_custom_command and add_custom_target to normalize slashes
of DEPENDS files up front. This approach subsumes the above-mentioned
special case so remove the one line added for it but keep its test.
Extend the CustomCommand test to check that slash count mismatches
between custom command OUTPUT and DEPENDS can still be linked correctly.
A search-and-replace in commit 8d32d229 (make commands lower case by
default, 2007-10-10) accidentally changed the variable reference
CMAKE_INCLUDE_DIRECTORIES_BEFORE to CMAKE_include_directories_BEFORE.
Change it back.
The Cray Fortran compiler started using module init symbols in version 7.3.2.
Starting in commit 71287734 (Teach FortranC interface for Intel, PGI, and gcc
4.2, 2009-08-05) we provide C versions of the module init symbols so that the
detection executable can link when the C versions of the module-mangled symbols
are picked up.
If no C module-mangled symbol matches then we cannot let the C module init
symbol appear because it will be duplicated by the Fortran copy that provides
the module-mangled symbol. This was first handled for the PathScale compiler
in commit 21faaa5d (FortranCInterface: Fix PathScale detection, 2010-01-22) and
commit 46858720 (FortranCInterface: Fix PathScale detection again, 2010-02-16).
Handle it now for the Cray compiler too.
The curses dialog (ccmake) allows variables to be specified on the
command line. If any of these variables is used during any configure
iteration or during generate we must not warn about it.
The Qt dialog (cmake-gui) allows variables to be added and removed in
the GUI interactively. If a variable is added, removed, and then added
again we must still warn if it is unused.
Set target property RUNTIME_OUTPUT_DIRECTORY explicitly on ProcessFwd9x
and EncodeExecutable so that we know exactly where the executables will
exist on disk.
At some point in the past VS 2010 failed some tests with custom commands when
relative paths were not used. It seems that those problems have been fixed.
However, the relative paths apparently are appended to the current working
directoy before vs accesses the file. So, with a long path, relative paths
cause it to create a combined path that is too long.
