Brad King 6c613b433c Handle usr-move without forcing absolute paths (#14041)
In commit 0c727b90 (install(EXPORT): Force absolute paths for usr-move,
2013-03-08) and commit d4774140 (configure_package_config_file: force
absolute paths for usr-move, 2013-01-24) we supported Linux
distributions implementing the "/usr move" by assuming that installation
to (/usr)?/lib(64)? represents a non-relocatable system package.

When cross-compiling one may prepare a package for installation into a
system location on a target machine but install the package files on the
*host* machine inside another path for use with CMAKE_FIND_ROOT_PATH.
In this case the package development files must still be relocatable.

Handle "/usr move" with a new approach that works with relocatable
files.  Teach configure_package_config_file and install(EXPORT) to
generate special logic in a package configuration file or targets file
for installation under (/usr)?/lib(64)?.  Teach the file to recognize
when it is loaded through a symlink that refers to the same realpath as
its original install destination.  In such a case, use the original
install prefix.  Otherwise, compute the prefix relative to the current
file location to make it relocatable.

Stephen Kelly af81a3c31b install(EXPORT): Ensure clean INTERFACE_INCLUDE_DIRECTORIES
Check that source and binary directories are not part of the
INTERFACE_INCLUDE_DIRECTORIES for installed IMPORTED targets.

This is limited to directories which do not contain generator
expressions to evaluate. Such paths can only be checked at time
of use of the imported target, which will be done in a follow up
patch.

Brad King 0c727b906a install(EXPORT): Force absolute paths for usr-move
If the absolute install(EXPORT) destination for the CMAKE_INSTALL_PREFIX
used during configuration is under (/usr)?/lib(64)? then assume the
current build is for a system package installation instead of a
relocatable distribution.  Generate an absolute path for _IMPORT_PREFIX
in the target exports file instead of generating code to compute the
value relative to the file location.  This is necessary for
distributions implementing a move to /usr such as:

 https://wiki.archlinux.org/index.php/DeveloperWiki:usrlib
 "All files in the /lib directory have been moved to /usr/lib and now
  /lib is a symlink to usr/lib."

The relative path computation is not reliable because the targets file
could be installed through cross-prefix a symlink and loaded without it
or vice versa.

A similar change was made for package configuration file generation by
commit d4774140 (configure_package_config_file: force absolute paths for
usr-move, 2013-01-24).

Stephen Kelly f5b1980fb2 Populate the ExportedTargets member early in GenerateMainFile
The member variable is checked to determine whether to call
HandleMissingTarget(). As that could be called during the loop in
the comming commits, ensure that it contains all targets being
exported.

Stephen Kelly bf2ddceb4e Generate an early-return guard in target Export files.
Previously it was necessary for writers of Config files
which incude exported target files to write the guard themselves, but
this was not immediately obvious or documented. Options for them
would be to use a variable, or an INHERITED directory property in an
effort to avoid accidental name clashes in all contexts in
which find_package can be used.

Getting this right requires boiler plate code, so generate a simpler
check automatically instead.

Alex Neundorf 0cfd055acd exports: move the handling of missing targets into subclasses
Before, cmExportFileGenerator::ComplainAboutMissingTarget() was a virtual
function which had to be implemented in the subclasses. It is not
anymore. Instead, there is now a virtual function
HandleMissingTargets(), which is implemented in the two subclasses.
This makes e.g. dealing correctly with APPEND mode easier.

Alex Neundorf 8b5f448ba6 exports: first try at error handling if a target is missing
Now, if an imported target depends on a library which must come
from some other export set, cmake generates a check which errors
out if that target does not exist. I guess instead of completely
erroring out it would be better to only make the find_package() fail.

Alex Neundorf 87f4c01910 exports: accept a missing target if it is exported exactly once
If a target is exported, and a library it depends on is not part
of the same export set, before this patch cmake errored out.
With this patch, it now checks whether the missing target
is exported somewhere else exactly once, and accepts in this
case (because then it can determine the namespace for the
missing target and use this).

Alex Neundorf a2be068c75 install(EXPORT): Enforce existence of imported target files
Typical <package>Config.cmake files for find_package() rely only on the
files generated by install(EXPORT).  They might be wrong, for whatever
reasons, like people manually deleted files, projects were packaged
wrong by distributions, whatever.  To protect against this, add checks
that the file locations we are importing actually exist on disk.

  - Created LINK_INTERFACE_LIBRARIES and related properties
  - Exported targets get the interface libraries as their

    an error when a linked target is not included since
    the user can change the interface libraries instead
    of adding the target.
