Bug#735592: llvm-3.5-dev: LLVM/Clang CMake package files missing

[Brad King]

Package: llvm-3.5-dev
Version: 1:3.5~svn197556-1
Severity: normal

Dear Maintainer,

The issue reported in archived bug #701153 is not fully resolved.
The main problem still exists as of llvm-3.5-dev 1:3.5~svn197556-1.

The cmake/modules/*.cmake files from the llvm source are installed
including a file called "LLVM-Config.cmake".  However, the files
needed to use CMake to build against LLVM as documented here:

 http://llvm.org/docs/CMake.html#embedding-llvm-in-your-project

are not installed.  These files are:

 LLVMConfig.cmake        = package configuration file
 LLVMConfigVersion.cmake = package version file

They are produced during the CMake configuration process for building
LLVM itself.  Their purpose is to hold information about what was built
and where it is installed.

Note that "LLVM-Config.cmake" is *not* the same as "LLVMConfig.cmake".
The former is a module that upstream authors wrote to contain some
CMake-language API code.  The latter is a CMake "package configuration
file" that is located and loaded by applications using

 find_package(LLVM)

or

 find_package(LLVM CONFIG REQUIRED)

in their CMake code as shown in the LLVM documentation.  Without the
missing files the applications fail to build with errors like that
shown below.

-Brad


CMake Error at CMakeLists.txt:36 (find_package):
  Could not find a package configuration file provided by "LLVM" with any of
  the following names:

    LLVMConfig.cmake
    llvm-config.cmake

  Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set
  "LLVM_DIR" to a directory containing one of the above files.  If "LLVM"
  provides a separate development package or SDK, be sure it has been
  installed.
