v3.4.1
Add checking if _FILE_OFFSET_BITS macro needed for large files.
Fix typo in CheckFileOffsetBits
A few Cmake build improvements from Issue 48: * Use the path holding the current file to make the build/cmake/*.cmake files more independent * Use CMAKE_CURRENT_SOURCE_DIR in the top-level CMakeLists.txt to locate the macro files and the version file.
Improve cmake detecting a function on linux. The GNU C library defines stub functions(chflags, fchflags..), and so cmake detecting the function process found out that stub function. This commit avoid detecting the stub function.
Clean up the top level a bit by moving the auxiliary cmake files down into build/cmake and the windows build files down into build/windows. I intend to do the same with the autoconf files, but that will require a little more creativity.
Fix the CMake build on systems that lack a C++ compiler. libarchive doesn't need C++, so we should be able to build on systems that don't have a C++ compiler.
Allow library installation to be disabled in CMake
Add check for finding libgcc.
Use cmake module similar to FindLZMA.cmake to find Nettle include dir and library.
Provide better check for when libpcreposix is to be used for regex support.
Include coverage script if ENABLE_COVERAGE is set
Add missing HAVE_UNLINKAT to build/cmake/config.h.in
