We previously used cURL to support HTTP proxies. Now that we've added this support natively, we can remove the curl dependency.

Increase the WIN32_WINNT level to 0x0600, which enables support for new APIs from Windows 6.0 (Vista). We had previously set this to 0x0501, which was Windows XP. Although we removed XP support many years ago, there was no need to update this level previously. We're doing so now explicitly so that we can get support for the `CreateSymbolicLink` API.

This performs a compile-check by using CMake support, to differentiate the GNU version from the BSD version of qsort_r. Module taken from 4f252abea5f1d17c60f6ff115c9c44cc0b6f1df6, which I've checked against CMake 2.8.11.

While the aim of libgit2 was to conform to C90 code, we never instructed the compiler to enforce C90 compliance. Thus, quite a few violations were able to get into our code base, which have been removed with the previous commits. As we are now able to build libgit2 with C90 enforced, we can set the C_STANDARD property for our own build targets. Note that we explicitly avoid setting the C standard for our third-party dependencies. At least the zlib target does not build with C90 enforced, and we do not want to fix them by deviating from upstream. Thus we simply enforce no standard for them.

While we want to enforce strict C90 mode, this may cause issues with system provided header files which are themselves not strictly conforming. E.g. if a system header has C++ style comments, a compiler in strict C90 mode would produce an error and abort the build. As the user most likely doesn't want to change the system header, this would completely break the build on such systems. One example of this is mbedtls, which provides such header files. The problem can be worked around by distinguishing between system-provided and project-provided include directories. When adding include directories via "-isystem" instead of "-I", the compiler will skip certain checks and print out less warnings. To use system includes, we can simply add the "SYSTEM" flag to CMake's `INCLUDE_DIRECTORIES` and `TARGET_INCLUDE_DIRECTORIES` functions. Note that we have to split the include directories into two variables because of this, as we definitely still want to check for all warnings produced by our own header files.

mbedTLS has no pkgconfig file, hence we can't require it. For now, pass its link flags as our own.

With the recent change of always resolving pkg-config libraries to their full path, we do not have to manage the LIBGIT2_LIBDIRS variable anymore. The only other remaining user of LIBGIT2_LIBDIRS is winhttp, which is a CMake-style library target and can thus be resolved by CMake automatically. Remove the variable to simplify our build system a bit.

Libraries found by CMake modules are usually handled with their full path. This makes linking against those libraries a lot more robust when it comes to libraries in non-standard locations, as otherwise we might mix up libraries from different locations when link directories are given. One excemption are libraries found by PKG_CHECK_MODULES. Instead of returning libraries with their complete path, it will return the variable names as well as a set of link directories. In case where multiple sets of the same library are installed in different locations, this can lead the compiler to link against the wrong libraries in the end, when link directories of other dependencies are added. To fix this shortcoming, we need to manually resolve library paths returned by CMake against their respective library directories. This is an easy task to do with `FIND_LIBRARY`.

We might want OpenSSL to be the implementation for SHA-1 and/or TLS. If we only want it for TLS (e.g. we're building with the collision-detecting SHA-1 implementation) then we did not indicate this to the systems including us a static library. Add OpenSSL to the list also during the TLS decision to make sure we say we should link to it if we use it for TLS.

It is indeed a list of dependencies for those which include the static archive. This is in preparation for adding two possible places where we might add openssl as a dependency.

Right now, if SHA1DC is disabled, the SHA1 backend is mostly chosen based on which system libgit2 is being compiled on and which libraries have been found. To give developers and distributions more choice, enable them to request specific backends by passing in a `-DSHA1_BACKEND=<BACKEND>` option instead. This completely replaces the previous auto-selection.

Instead of forcing iconv support on macOS (by forcing `USE_ICONV` on), honor the `USE_ICONV` option only on macOS. Although macOS includes iconv by default, some macOS users may have a deficient installation for some reason and they should be provided a workaround to use libgit2 even in this situation. iconv support is now disabled entirely on non-macOS platforms. No other platform supports core.precomposeunicode, and iconv should never be linked.

Under some circumstances the installed / system version of zlib may not be desirable due to being too old or buggy. This patch adds the option `USE_BUNDLED_ZLIB` that will cause the bundled version of zlib to be used. We may also want to add similar functionality to allow the user to select other bundled 3rd-party dependencies instead of using the system versions. /cc @pks-t @ethomson

This allows us to only link against CoreFoundation when using the SecureTransport backend
Etienne Samson committed -
It defaults to ON, e.g. "pick whatever default is appropriate for the platform". It accepts one of SecureTransport, OpenSSL, WinHTTP, or OFF. It errors if the backend library couldn't be found.

Due to our split of CMake files into multiple modules, we had to replace some uses of the `${CMAKE_CURRENT_SOURCE_DIR}` and `${CMAKE_CURRENT_BINARY_DIR}` variables and replace them with `${CMAKE_SOURCE_DIR}` and `${CMAKE_BINARY_DIR}`. This enabled us to still be able to refer to top-level files when defining build instructions inside of a subdirectory. When replacing all variables, it was assumed that the absolute set of variables is always relative to the current project. But in fact, this is not the case, as these variables always point to the source and binary directory as given by the top-levl project. So the change actually broke the ability to include libgit2 directly as a subproject, as source files cannot be found anymore. Fix this by instead using project-specific source and binary directories with `${libgit2_SOURCE_DIR}` and `${libgit2_BINARY_DIR}`.

CMake is unable to generate a correct Xcode project when trying to link libraries with only object libraries as its input. As our new build infrastructure makes heavy use of object libraries now, this affects our libgit2 library target, as well, leading to linking errors. Fix the issue by adding a dummy file to the libgit2 objects. As we always have the "features.h" header ready which contains defines only, we can simply link it into the resulting library without any effect whatsoever. This fixes building with Xcode.

Our bundled deps are being built as simple static libraries which are then linked into the libgit2 library via `TARGET_LINK_LIBRARIES`. While this works for a dynamically built libgit2 library, using this function to link two static libraries does not have the expected outcome of merging those static libraries into one big library. This leads to symbols of our bundled deps being undefined in the resulting libgit2 archive. As we have bumped our minimum CMake version to 2.8.11, we can now easily make use of object libraries for our bundled dependencies. So build instructions are still self-contained inside of the dependency directories and the resulting object libraries can just be added to the LIBGIT2_OBJECTS list, which will cause them to be linked into the final resulting static library. This fixes the issue of undefined symbols.

As we have bumped our minimum CMake version to 2.8.11, we can now unconditionally make use of object libraries. So remove the version check for the git2internal object library and always use it.

Distinguish variables keeping track of our internal libgit2 sources and the final objects which shall be linked into the library. This will ease the transition to use object libraries for our bundled dependencies instead of linking them in.

As observed by Edward Thomson, the libgit2 DLL built by Windows will not end up in the top-level build directory but instead inside of the 'src/' subdirectory. While confusing at first because we are actually setting the LIBRARY_OUTPUT_DIRECTORY to the project's binary directory, the manual page of LIBRARY_OUTPUT_DIRECTORY clears this up: There are three kinds of target files that may be built: archive, library, and runtime. Executables are always treated as runtime targets. Static libraries are always treated as archive targets. Module libraries are always treated as library targets. For non-DLL platforms shared libraries are treated as library targets. For DLL platforms the DLL part of a shared library is treated as a runtime target and the corresponding import library is treated as an archive target. All Windows-based systems including Cygwin are DLL platforms. So in fact, DLLs and import libraries are not treated as libraries at all by CMake but instead as runtime and archive targets. To fix the issue, we can thus simply set the variables RUNTIME_OUTPUT_DIRECTORY and ARCHIVE_OUTPUT_DIRECTORY to the project's root binary directory.

With c26ce784 (Merge branch 'AndreyG/cmake/modernization', 2017-06-28), we have recently introduced a regression in the way we are searching for headers. We have made sure to always include our own headers first, but due to the changes in c26ce784 this is no longer guaranteed. In fact, this already leads the compiler into picking "config.h" from the "deps/regex" dependency, if it is used. Fix the issue by declaring our internal include directories up front, before any of the other search directories is added.

To fix leaking build instructions into different targets and to make the build instructions easier to handle, create a new CMakeLists.txt file containing build instructions for the libgit2 target. By now, the split is rather easy to achieve. Due to the preparatory steps, we can now simply move over all related build instructions, only needing to remove the "src/" prefix from some files.

There are quite some uses of the variables "${CMAKE_CURRENT_SOURCE_DIR}" and "${CMAKE_CURRENT_BINARY_DIR}" where they are not appropriate. Convert these sites to instead use the variables "${CMAKE_SOURCE_DIR}" and "${CMAKE_BINARY_DIR}", which instead point to the project's root directory. This will ease splitting up the library build instructions into its own subdirectory.
