2ccca05 Run PDBDirectoryAndName test on MSVC and Intel
efc83b3 Document that PDB_(NAME|OUTPUT_DIRECTORY) are ignored for VS 6
b294457 Verify that PDB_(NAME|OUTPUT_DIRECTORY) are honored in test
3f60dbf Add PDB_OUTPUT_DIRECTORY and PDB_NAME target properties (#10830)
This way the name of the searched package can be accessed in find-modules,
config-files and more importantly in generated target export files.
This is now used when a target export file detects that a required
target does not exist.
Alex
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
Move it out of the condition that also accepts MinGW/MSYS.
Teach the test to allow the Intel for Windows compiler but
do not verify the results because the compiler does not
seem to write PDB output in all cases.

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
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
If a config-file sets <package>_FOUND to FALSE, it can now give a reason
using the variable <package>_NOT_FOUND_MESSAGE, which is used by cmFindPackage
and FPHSA.
Alex
The remainder of this method depends on the target existing (otherwise
the includes container would be empty), so make the code a little more
readable.
Prevent constructs like:
... INCLUDE_DIRECTORIES "$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>"
Indirect self-references (cycles) are also prevented here, but
indirect generator expression references of any kind are not
possible yet anyway.
There are two overloads, so that it can use the operational
target when a target property is being evaluated, and a target
can alternatively be specified by name.
At this point, the generators don't chain. That comes later.
Generator expressions for comparing strings, evaluating
strings as booleans, and for creating literal right-angle-brackets
and commas are added. Those may be needed in some cases
where they appear in literals.
Since FPHSA is called for multiple compiler languages with "MPI_${lang}"
rather than just "MPI", make sure variables for controlling QUIET,
REQUIRED and VERSION are propagated with names prefixed by MPI_${lang}
as well, rather than just MPI.
The find_package call sets up the values of MPI_FIND_REQUIRED and friends,
but these calls to FPHSA need MPI_${lang}_FIND_REQUIRED and friends in
order to function as intended.
