[LLVMdev] migrating from autoconf to cmake+ninja

I want to start using cmake+ninja instead of autoconf for configuring
and building llvm from svn, but I have no idea how to map my existing
list of autoconf flags to cmake.

Here's how I run ./configure right now in the top directory:
PREFIX=_some_prefix_dir_ \
    ../llvm/configure \
    --prefix=$PREFIX \
    --libdir=$PREFIX/lib/llvm \
    --sysconfdir=$PREFIX/etc \
    --enable-shared \
    --enable-targets=all \
    --disable-expensive-checks \
    --disable-debug-runtime \
    --disable-assertions \
    --with-binutils-include=/usr/include \
    --enable-optimized

Is it possible to map this to cmake flags and if yes how?

Platform is linux-x86_64 and revision is release_35 branch.

If there's superfluous flags please do tell and I'll remove them.

Also is there a flag to skip tests?

Is building lld on linux supported? I tried including lld in the build
and it failed:
llvm[4]: Linking Release unit test CoreTest (without symbols)
/tmp/llvm/build/Release/lib/libgtest_main.a(TestMain.o): In function `main':
/tmp/llvm/llvm/utils/unittest/UnitTestMain/TestMain.cpp:(.text.main+0x28):

const* const*, char const*)'

[LLVMdev] migrating from autoconf to cmake+ninja

prefix = CMAKE_INSTALL_PREFIX
enabled-shared = BUILD_SHARED_LIBS
targets = LLVM_TARGETS_TO_BUILD (defaults to all, or use a semicolon separated
list)
disable-assertions = LLVM_ENABLE_ASSERTIONS (obviously inverted ;)

I don't believe the others have direct equivalents, however debug/optimized
is chosen via CMAKE_BUILD_TYPE

Thank you. I found
http://llvm.org/docs/CMake.html#options-and-variables and gonna
try out cmake -G ninja.
