In cmake, dependencies on generated files require some sophistication in the build system. At build time, files are parsed to determine which headers they depend on and these dependencies are injected into the build system. This works well with ninja, but has some constraints with the makefile generator. According to the cmake documentation, this only works reliably within the same directory.
This patch expands the usage of mlir-headers to include all generated headers and adds an mlir-generic-headers target which triggers generation of dialect-independent headers. These targets are used to express dependencies on generated headers. This is mostly handled in AddMLIR.cmake and only a few CMakeLists.txt files need to change.

Define MLIR_MAIN_INCLUDE_DIR, as it was not set anywhere.
Set MLIR_MAIN_SRC_DIR to the actual "source directory", and not the
"include directory" (as currently set).

Setting MLIR_TABLEGEN_EXE would prevent building the native tool which is used in cross-compiling

Putting this up mainly for discussion on
how this should be done. I am interested in MLIR from
the Julia side and we currently have a strong preference
to dynamically linking against the LLVM shared library,
and would like to have a MLIR shared library.
This patch adds a new cmake function add_mlir_library()
which accumulates a list of targets to be compiled into
libMLIR.so. Note that not all libraries make sense to
be compiled into libMLIR.so. In particular, we want
to avoid libraries which primarily exist to support
certain tools (such as mlir-opt and mlir-cpu-runner).
Note that the resulting libMLIR.so depends on LLVM, but
does not contain any LLVM components. As a result, it
is necessary to link with libLLVM.so to avoid linkage
errors. So, libMLIR.so requires LLVM_BUILD_LLVM_DYLIB=on
FYI, Currently it appears that LLVM_LINK_LLVM_DYLIB is broken
because mlir-tblgen is linked against libLLVM.so and
and independent LLVM components.
Previous version of this patch broke depencies on TableGen
targets. This appears to be because it compiled all
libraries to OBJECT libraries (probably because cmake
is generating different target names). Avoiding object
libraries results in correct dependencies.

This pass would currently build, but fail to run when this backend isn't
linked in. On the other hand, we'd like it to initialize only the NVPTX
backend, which isn't possible if we continue to build it without the
backend available. Instead of building a broken configuration, let's
skip building the pass entirely.

Summary: Right now the path for each lib in whole_archive_link when MSVC is used as the compiler is not a full path - and it's not even the correct path when VS is used to build. This patch sets the lib path to a full path using CMAKE_CFG_INTDIR which means the path will be correct regardless of whether ninja, make or VS is used and it will always be a full path.

This is needed to consume mlir after it has been installed of the source
tree. Without this, consuming mlir results a build error.

The issue is that /WHOLEARCHIVE is interpreted differently in LLD, which needs the same exact path as the .lib; whereas link.exe can take the library name, withoutout a path or extension, if that was already supplied on the cmd-line. I'll write a follow-up patch to fix the issue in LLD.
Currently when you build the `install` target, TableGen files don't get
installed.
TableGen files are needed when authoring new MLIR dialects, but right
now they're missing when using the pre-built binaries.

This CL allows specifying an additional name for specifying the .td file that is used to generate the doc for a dialect. This is necessary for a dialect like Linalg which has different "types" of ops that are used in different contexts.
This CL also restructures the Linalg documentation and renames LinalgLibraryOps -> LinalgStructuredOps but is otherwise NFC.

on a CUDA capable GPU. For this to work, a working CUDA install is required
and the build has to be configured with MLIR_CUDA_RUNNER_ENABLED set to 1.

The -all_load flag will apply to all future libraries added on the command line,
while the -force_load flag only applies to the next library. Using the latter
