----------------------------
Summary: [C++] Fix CMake script to be used inside another project
Key: ORC-1833
URL: https://issues.apache.org/jira/browse/ORC-1833
Project: ORC
Issue Type: Bug
Components: C++
Reporter: Gang Wu
Assignee: Gang Wu
The change to add support for exporting CMake config and target has introduced
some minor issues when the ORC C++ library is used inside a larger CMake
project. Mainly there are three issues:
# We should prepend (not append) our CMake modules so we always use our own
modules when there are naming conflict.
# Do not use CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR because they are tied to
the root project and it is no longer ORC project when we are inside another
project.
# Add orc_ prefix to our CMake functions to avoid potential conflict.
