llvm-3.7 doesn't include libraries in LLVMExports.cmake

[ppohja@…]

In LLVM-3.6 all the exported libraries were declared with add_library() and their file system location in LLVMExpores.cmake. When trying to compile software that requires LLVM 3.7 (cpp-ethereum), I am getting a big number of errors like this:

CMake Error at /opt/local/libexec/llvm-3.7/share/llvm/cmake/LLVMExports.cmake:10 (set_property):
  set_property could not find TARGET LLVMSupport.  Perhaps it has not yet
  been created.
Call Stack (most recent call first):
  /opt/local/libexec/llvm-3.7/share/llvm/cmake/LLVMConfig.cmake:59 (include)
  evmjit/CMakeLists.txt:51 (find_package)

It looks like the version of LLVMExports.cmake does not include the libraries provided by LLVM. I can get rid of these error messages by running

grep TARGET errlog |cut -d" " -f 8|cut -d"." -f 1 |sort|uniq|awk '{print "add_library(" $1 " STATIC IMPORTED)"}'

and adding the output to the file LLVMExports.cmake.

My target software declares LLVM's usage as this: llvm_map_components_to_libnames(LLVM_LIBS core support mcjit x86asmparser x86codegen ipo) - and now my compilation fails on the missing component 'core'.

Don't know if this is an LLVM or macports issue.

Please don't CC yourself - reporters are automatically notified of changes.

Instead, remember to CC all maintainers and fill out the Port field next time.

This looks like an upstream issue.

Do you see issues using llvm-3.8? I pushed changes today that move the port onto the cmake based build system instead of automake.

No response. Closing.
