Hello, I am having some difficulty trying to add an external project, in this particular case the VTK (Visualization Toolkit) project, to my own project using the *ExternalProject_Add *command. My goal is to download the project from the git repository to a *third_party_folder* in my repo and then link my executables against its targets.
My directory structure is as follows - CMakeLists.txt - src_folder - CMakeLists.txt - main.cpp - third_party_folder - CMakeLists.txt - cmake_folder - External-VTK.cmake ## CMakeLists.txt cmake_minimum_version(VERSION 3.1) project(MyProj) list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake_folder") include(ExternalProject) add_subdirectory(src_folder) add_subdirectory(third_party_folder) ## third_party_folder/CMakeLists.txt include(External-VTK) ## cmake_folder/External-VTK.cmake ExternalProject_Add(VTK GIT_REPOSITORY https://github.com/Kitware/VTK.git GIT_TAG master SOURCE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/VTK" BINARY_DIR "${CMAKE_CURRENT_BINARY_DIR}/VTK") ## src_folder/CMakeLists.txt add_executable(CylinderExample main.cpp) target_link_libraries(CylinderExample PRIVATE ${VTK_LIBRARIES}) vtk_module_autoinit( TARGETS CylinderExample MODULES ${VTK_LIBRARIES}) This still does not seem to be doing what I want, so I was wondering if anyone could offer some advice. I am unsure of how to get the outputted targets from an external project. Thank you. Nick
