CMake generates the exports file wrongly if the CMAKE_BUILD_TYPE is
unset for multi-configuration generators.
The generated file lib/cmake/polly/PollyExports-all.cmake then contains:
set_target_properties(LLVMPolly PROPERTIES
IMPORTED_LOCATION_ my_build_dir/lib/LLVMPolly.so)
set_target_properties(Polly PROPERTIES
IMPORTED_LOCATION_ my_build_dir/lib/libPolly.a)
This patch conditionalizes the underscore.

CMake insists that for each target, one uses only the non-keyword
version of target_link_library
target_link_library(mytarget lib)
or the one with PUBLIC/PRIVATE/INTERFACE keyword:
target_link_library(mytarget PUBLIC lib)
Otherwise, CMake fails with the error message:
The keyword signature for target_link_libraries has already been used with
the target "mytarget". All uses of target_link_libraries with a target
must be either all-keyword or all-plain.
Change all occurances of target_link_library to the newer keyworded
version to avoid such errors. Some already have been changed in r319840,
but might not be sufficient for all build configurations to build
the doxygen manual.

find_library(lib) stores the result in the variable "lib", which is also
cached in CMakeCache.txt. This could theoretically conflict if jsoncpp
required two libraries, which each would get cached as "lib". Use a
more descriptive and disambiguative "jsoncpp_${libname}" for that.
llvm-svn: 308289
Use ${libname} instead of ${lib}. By a coincidence, this worked
because ${lib} also the variable used for finding the libjsoncpp.so
full path.
llvm-svn: 308288
pkg_search_module(JSONCPP) should set
JSONCPP_LIBDIR/JSONCPP_LIBRARY_DIRS to where the libjsoncpp.so can be
found. However, on Ubuntu 14.04 LTS (Trusty Tahr) it returns /usr/lib
while the libjsoncpp library can be found at
/usr/lib/x86_64-linux-gnu/libjsoncpp.so. Thus, while searching for
the full path of the jsoncpp library, it is not found.
JSONCPP_LIBDIR is correctly set to /usr/lib/x86_64-linux-gnu on e.g.,
Ubuntu 16.04 LTS (Xenial Xerus )
Fix by removing the NO_DEFAULT_PATH flag, in order to search the system
default paths even if the library is not found in
JSONCPP_LIBDIR/JSONCPP_LIBRARY_DIRS.
This fixes bug llvm.org/PR33798.

Summary:
As of now, Polly uses llvm-config to set up LLVM dependencies in an out-of-tree build.
This is problematic for two reasons:
1) Right now, in-tree and out-of-tree builds in fact do different things. E.g., in an in-tree build, libPolly depends on a handful of LLVM libraries, while in an out-of-tree build it depends on all of them. This means that we often need to treat both paths seperately.
2) I'm specifically unhappy with the way libPolly is linked right now, because it just blindly links against all the LLVM libs. That doesn't make a lot of sense. For instance, one of these libs is LLVMTableGen, which contains a command line definition of a -o option. This means that I can not link an out-of-tree libPolly into a tool which might want to offer a -o option as well.
This patch (mostly) drop the use of llvm-config in favor of LLVMs exported cmake package. However, building Polly with unittests requires access to the gtest sources (in the LLVM source tree). If we're building against an LLVM installation, this source tree is unavailable and must specified. I'm using llvm-config to provide a default in this case.

This patch adds an option to build against a version of libisl already
installed on the system. The installation is autodetected using the
pkg-config file shipped with isl.
The detection of the library is in the FindISL.cmake module that creates
an imported target.

The flag -fvisibility=hidden flag was used for the integrated Integer
Set Library (and PPCG) to keep their definitions local to Polly. The
motivation was the be loaded into a DragonEgg-powered GCC, where GCC
might itself use ISL for its Graphite extension. The symbols of Polly's
ISL and GCC's ISL would clash.
The DragonEgg project is not actively developed anymore, but Polly's
unittests need to call ISL functions to set up a testing environment.
Unfortunately, the -fvisibility=hidden flag means that the ISL symbols
are not available to the gtest executable as it resides outside of
libPolly when linked dynamically. Currently, CMake links a second copy
of ISL into the unittests which leads to subtle bugs. What got observed
is that two isl_ids for isl_id_none exist, one for each library
instance. Because isl_id's are compared by address, isl_id_none could
happen to be different from isl_id_none, depending on which library
instance set the address and does the comparison.
Also remove the FORCE_STATIC flag which was introduced to keep the ISL
symbols visible inside the same libPolly shared object, even when build
with BUILD_SHARED_LIBS.

We cannot built ISL as shared object because we build it with
-fvisibility=hidden; The created shared object would have no accessible symbols.
The reason it is built with -fvisibility=hidden is because opt/clang might load
other libraries that have ISL embedded and whose' symbols would conflict with
Polly's private ISL. This could happend with Draggonegg.
In the future we might instead statically link PollyISL into the Polly shared
object to avoid installing the static library.

Static libraries where installed into "lib${LLVM_LIBDIR_SUFFIX}" while
shared ones into "lib". I found no justification for this behaviour.
This patch changes both types of libraries to be install into
"lib${LLVM_LIBDIR_SUFFIX}". LLVM and clang use the same behaviour.
This fixes llvm.org/PR27305.

Refactor all ISL-related cmake build instructions into its own
CMakeLists.txt and build as a separate library.
This is useful to apply ISL-related build flags to ISL only and not to
Polly's files. Also, it the separation of both projects becomes clearer.
Proposed name of the library is Polly_isl. It is not "isl" to avoid
mix-up with potentially installed libisl.{a|so}.
Tested configurations:
- Windows with cmake 3.2
- Ubuntu with cmake 3.0.2
- Ubuntu with cmake 3.0.2 BUILD_SHARED_LIBS on
- Ubuntu with cmake 2.8.12.2 (LLVM minimum version)
- Ubuntu out-of-LLVM-tree

With this patch Polly is always GPL-free (no dependency on GMP any more). As a
result, building and distributing Polly will be easier. Furthermore, there is no
need to tightly coordinate isl and Polly releases anymore.
We import isl b3e0fa7a05d as well as imath 4d707e5ef2. These are the git
versions Polly currently was tested with when using utils/checkout_isl.sh. The
imported libraries are both MIT-style licensed.
We build isl and imath with -fvisibility=hidden to avoid clashes in case other
projects (such as gcc) use conflicting versions of isl. The use of imath can
temporarily reduce compile-time performance of Polly. We will work on
performance tuning in tree.
Patches to isl should be contributed first to the main isl repository and can
then later be reimported to Polly.
This patch is also a prerequisite for the upcoming isl C++ interface.
