As noted in #128, if clock_gettime is provided by librt then it does not
end up being linked into the static libuv.a binary. This might be
considered a bug in libuv but we can address it here.
Detect if librt provides the clock_gettime symbol and, if so, append it
to the list of libraries linked into nvim. On non-librt systems the
behaviour should be as before.
We use the standard CMAKE_PREFIX_PATH variable to pass the location of
.deps as a search location on the command line. There is now no need for
explicitly hard-coding it.
CMake ships with a standard FindThreads module which can be used to a)
test for a threading library and b) confirm that it is pthread. It also
allows the hard-coding of the threading library name to be removed from
``src/CMakeLists.txt``.
Make it an error not to have a pthread library installed and indicate to
CMake that we strongly prefer pthread to any other platform threading
library.
- Cleanup source tree, leaving only files necessary for compilation/testing
- Process files through unifdef to remove tons of FEAT_* macros
- Process files through uncrustify to normalize source code formatting.
- Port the build system to cmake
