This is controlled by the following CMake settings (see <a href="https://llvm.org/docs/CMake.html#llvm-specific-variables" rel="noreferrer" target="_blank">https://llvm.org/docs/CMake.html#llvm-specific-variables</a>):<br>
<br>
LLVM_BUILD_LLVM_DYLIB:BOOL<br>
<br>
If enabled, the target for building the libLLVM shared library is added. This library contains all of LLVM’s components in a single shared library. Defaults to OFF. This cannot be used in conjunction with BUILD_SHARED_LIBS. Tools will only be linked to the libLLVM shared library if LLVM_LINK_LLVM_DYLIB is also ON. The components in the library can be customised by setting LLVM_DYLIB_COMPONENTS to a list of the desired components. This option is not available on Windows.<br>
<br>
LLVM_LINK_LLVM_DYLIB:BOOL<br>
<br>
If enabled, tools will be linked with the libLLVM shared library. Defaults to OFF. Setting LLVM_LINK_LLVM_DYLIB to ON also sets LLVM_BUILD_LLVM_DYLIB to ON. This option is not available on Windows.<br>
<br>
E.g. these options are off by default (probably because it saves build time, but I'm just guessing here), and are not available on Windows (for reasons unknown to me).<br>
<br>
<br>

<br>
I don't know about that, but maybe Hans Wennborg has more information.<br>

<br>
Either you can link against distro-provided LLVM dynamic libraries, like those shipped by Debian and Ubuntu, or you can link against the static libraries in the release tarballs.<br>
<br>
But obviously, you could always build them yourself, and ship them with your tools. This would give you the most flexibility.<br>
