[llvm-dev] Embedding llvm as a git submodule in Project

[Timo Janssen via llvm-dev]

Hi,


I am sorry but I really am not good with cmake yet.

I made one mistake I used MODULE instead of CONFIG in find_package.

But even with CONFIG I doesn't work for me.


Here my CMakeLists.txt:


cmake_minimum_required(VERSION 3.5.1)
project(SimpleProject)

find_package(LLVM REQUIRED CONFIG PATHS 
"${CMAKE_CURRENT_SOURCE_DIR}/llvm/cmake$

message(STATUS "Found LLVM ${LLVM_PACKAGE_VERSION}")
message(STATUS "Using LLVMConfig.cmake in: ${LLVM_DIR}")

include_directories(${LLVM_INCLUDE_DIRS})
add_definitions(${LLVM_DEFINITIONS})

add_executable(simple-tool main.cpp)

llvm_map_components_to_libnames(llvm_libs support)

target_link_libraries(simple-tool ${llvm_libs})


Here part of the cmake output in terminal:

CMake Error at CMakeLists.txt:4 (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.


-- Configuring incomplete, errors occurred!
See also "/home/timoo/Schreibtisch/build/CMakeFiles/CMakeOutput.log"


I added the PATHS to find_package becouse the command must find the files.

In the llvm/cmake/modules dircotry are:

LLVM-Config.cmake (instead of lower case) and

LLVMConfig.cmake.in (.in added at end)


So what must I do?
