Michal Gorny 51dd7d27dc cmake: Install the OCaml libraries into a more correct path Add a OCAML_INSTALL_PATH variable that can be used to control the install path for OCaml libraries. The new variable defaults to ${OCAML_STDLIB_PATH}, i.e. the OCaml library path obtained from the OCaml compiler. Install libraries into "llvm" subdirectory. This fixes two issues: 1. OCaml library directories differ between systems, and 'lib/ocaml' is incorrect e.g. on amd64 Gentoo where OCaml is installed in 'lib64/ocaml'. Therefore, obtain the library path from the OCaml compiler using 'ocamlc -where' (which is already used to set OCAML_STDLIB_PATH), which is the method used commonly in OCaml packages. 2. The top-level directory is reserved for the standard library, and has precedence over local directory in search path. As a result, OCaml preferred the files installed along with previous LLVM version over the source tree when building a new version, resulting in two versions being mixed during the build. The new layout is used commonly by other OCaml packages, and findlib is able to find the LLVM libraries successfully.

README.txt

This directory contains LLVM bindings for the OCaml programming language
(http://ocaml.org).

Prerequisites
-------------

* OCaml 4.00.0+.
* ctypes 0.4+.
* oUnit 2+ (only required for tests).
* CMake (to build LLVM).

Building the bindings
---------------------

If all dependencies are present, the bindings will be built and installed
as a part of the default CMake configuration, with no further action.
They will only work with the specific OCaml compiler detected during the build.

The bindings can also be built out-of-tree, i.e. targeting a preinstalled
LLVM. To do this, configure the LLVM build tree as follows:

    $ cmake -DLLVM_OCAML_OUT_OF_TREE=TRUE \
            -DCMAKE_INSTALL_PREFIX=[OCaml install prefix] \
            [... any other options]

then build and install it as:

    $ make ocaml_all
    $ cmake -P bindings/ocaml/cmake_install.cmake
