b21c5408	2018-01-08T12:33:07	cmake: add openssl to the private deps list when it's the TLS implementation 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.
b85548ed	2018-01-08T12:30:50	cmake: treat LIBGIT2_PC_REQUIRES as a list 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.

70aa6146	2017-12-05T08:48:31	cmake: allow explicitly choosing SHA1 backend 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.

4969a672	2017-12-10T02:19:34	cmake: create a dummy file for Xcode Otherwise Xcode will happily not-link our git2 target, resulting in a "missing file" error when building eg. examples
bbb213c1	2017-11-11T13:19:24	cmake: let USE_ICONV be optional on macOS 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.
a0b0b808	2017-11-11T14:03:14	cmake: Allow user to select bundled zlib 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
c9bb68c2	2017-09-07T00:41:54	cmake: move Darwin-specific block around This allows us to only link against CoreFoundation when using the SecureTransport backend
9980be03	2017-09-06T22:13:58	cmake: Add USE_HTTPS as a CMake option 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.

4da74c83	2017-10-20T07:29:17	cmake: use project-relative binary and source directories 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}`.
0e709032	2017-10-09T10:55:02	cmake: fix linking in Xcode with object libraries only 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.
8c19969a	2017-09-06T07:38:48	cmake: fix static linking for bundled deps 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.
172a585f	2017-09-05T15:09:34	cmake: always use object library for git2internal 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.
1d9dd882	2017-09-05T15:06:29	cmake: distinguish libgit2 objects and sources 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.
a3a35473	2017-08-17T08:38:47	cmake: fix output location of import libraries and DLLs 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.
8a43161b	2017-07-05T12:18:17	cmake: always include our own headers first With c26ce7840 (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 c26ce7840 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.
e5c9723d	2017-06-30T18:12:02	cmake: move library build instructions into subdirectory 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.
