Alternativaly, you can utilize CMake's find_package + functionality. Here is an equivalent variant of snippet shown above:

+ +
+ 
+    find_package(LLVM)
+
+    if( NOT LLVM_FOUND )
+      message(FATAL_ERROR "LLVM package can't be found. Set CMAKE_PREFIX_PATH variable to LLVM's installation prefix.")
+    endif()
+
+    include_directories( ${LLVM_INCLUDE_DIRS} )
+    link_directories( ${LLVM_LIBRARY_DIRS} )
+
+    llvm_map_components_to_libraries(REQ_LLVM_LIBRARIES jit native)
+
+    target_link_libraries(mycompiler ${REQ_LLVM_LIBRARIES})
+
