Hi,
Adding find_package(Parquet REQUIRED) to CMakeLists.txt and
parquet_shared to target_link_libraries() will work:
---
project(TestLib)
cmake_minimum_required(VERSION 2.8.12)
set(CMAKE_MACOSX_RPATH 1)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/lib")
find_package(JlCxx)
get_target_property(JlCxx_location JlCxx::cxxwrap_julia LOCATION)
get_filename_component(JlCxx_location ${JlCxx_location} DIRECTORY)
set(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib;${JlCxx_location}")
message(STATUS "Found JlCxx at ${JlCxx_location}")
# Added:
find_package(Parquet REQUIRED)
add_library(testlib SHARED testlib.cpp)
# Added: parquet_shared
target_link_libraries(testlib JlCxx::cxxwrap_julia parquet_shared)
install(TARGETS
testlib
LIBRARY DESTINATION lib
ARCHIVE DESTINATION lib
RUNTIME DESTINATION lib)
---
You may need to add
-DCMAKE_MODULE_PATH=/PATH/TO/FindParquet.cmake option to
your cmake command line if you don't install Apache Parquet
by our Linux packages.
Thanks,
