Compile Cpp file which is using VTK library with CMake - c++

Question

I want to compile cpp source code in which VTK, Eigen, PETSc and dealII libraries are included. source files are located in src directory and header files in ìnclude directory.
The CMakeLists.txtfile is as follows:
cmake_minimum_required(VERSION 3.20.3)
project(ddm_library)
set (CMAKE_CXX_FLAGS "-Wsign-compare -Wno-unused-variable -Wno-unused-parameter -Wdeprecated-copy")
set(VTK_DIR /home/mehdi/myFolder/programming/lib/VTK-9.0.3/build)
# PkgConfig
find_package(PkgConfig)
# PETSc
if (PKG_CONFIG_FOUND)
pkg_check_modules(PETSC PETSc)
endif()
# include PETSC
if (PETSC_FOUND)
list(APPEND COMPILE_OPTIONS ${PETSC_CFLAGS})
include_directories(${PETSC_INCLUDE_DIRS})
set(LINK_FLAGS "${LINK_FLAGS} ${PETSC_LDFLAGS}")
list(APPEND LIBRARIES ${PETSC_LINK_LIBRARIES})
set(CMAKE_REQUIRED_FLAGS ${PETSC_CFLAGS})
set(CMAKE_REQUIRED_INCLUDES "${PETSC_INCLUDE_DIRS}")
endif()
# include Eigen
find_package (Eigen3 3.3 REQUIRED NO_MODULE)
# VTK library
find_package(VTK COMPONENTS
vtkCommonColor
vtkCommonCore
vtkCommonDataModel
vtkInteractionStyle
vtkRenderingContextOpenGL2
vtkRenderingCore
vtkRenderingFreeType
vtkRenderingGL2PSOpenGL2
vtkRenderingOpenGL2
vtkCommonCore
vtkCommonDataModel
vtkIOXML
QUIET
)
if (NOT VTK_FOUND)
message("Skipping StructuredGrid: ${VTK_NOT_FOUND_MESSAGE}")
return ()
endif()
message (STATUS "VTK_VERSION: ${VTK_VERSION}")
# dealII
FIND_PACKAGE(deal.II 9.3.0 QUIET
HINTS ${deal.II_DIR} ${DEAL_II_DIR} ../ ../../ $ENV{DEAL_II_DIR}
)
IF(NOT ${deal.II_FOUND})
MESSAGE(FATAL_ERROR "\n"
"*** Could not locate a (sufficiently recent) version of deal.II. ***\n\n"
"You may want to either pass a flag -DDEAL_II_DIR=/path/to/deal.II to cmake\n"
"or set an environment variable \"DEAL_II_DIR\" that contains this path."
)
ENDIF()
DEAL_II_INITIALIZE_CACHED_VARIABLES()
if (VTK_VERSION VERSION_LESS "8.90.0")
# old system
INCLUDE_DIRECTORIES(include ${VTK_USE_FILE} ${VTK_INCLUDE_DIRS} ${EIGEN3_INCLUDE_DIR})
file (GLOB LIB "src/*.cc")
ADD_LIBRARY(lib ${LIB})
vtk_module_autoinit(
TARGETS lib
MODULES ${VTK_LIBRARIES}
)
DEAL_II_SETUP_TARGET(lib)
add_executable(${PROJECT_NAME} MACOSX_BUNDLE "test/main.cc")
DEAL_II_SETUP_TARGET(${PROJECT_NAME})
target_link_libraries(${PROJECT_NAME} PRIVATE lib Eigen3::Eigen ${VTK_LIBRARIES})
else ()
# include all components
INCLUDE_DIRECTORIES(include ${VTK_USE_FILE} ${VTK_INCLUDE_DIRS} ${EIGEN3_INCLUDE_DIR})
file (GLOB LIB "src/*.cc")
ADD_LIBRARY(lib ${LIB})
vtk_module_autoinit(
TARGETS lib
MODULES ${VTK_LIBRARIES}
)
DEAL_II_SETUP_TARGET(lib)
add_executable(${PROJECT_NAME} MACOSX_BUNDLE "test/main.cc")
DEAL_II_SETUP_TARGET(${PROJECT_NAME})
target_link_libraries(${PROJECT_NAME} PRIVATE lib Eigen3::Eigen ${VTK_LIBRARIES})
# vtk_module_autoinit is needed
vtk_module_autoinit(
TARGETS ${PROJECT_NAME}
MODULES ${VTK_LIBRARIES}
)
endif ()
running cmd like
$ cmake -DCMAKE_BUILD_TYPE=Debug ..

I can not understand why I got such a error.

I modified the CMakeLists.txtby removing PRIVATEfrom target_link_librariesand add target_link_librariesfor lib, and the problem solved. The new CMakeLists.txt is look like this:
cmake_minimum_required(VERSION 3.20.3)
project(ddm_library)
set (CMAKE_CXX_FLAGS "-Wsign-compare -Wno-unused-variable -Wno-unused-parameter -Wdeprecated-copy")

# PkgConfig
find_package(PkgConfig)
# PETSc
if (PKG_CONFIG_FOUND)
pkg_check_modules(PETSC PETSc)
endif()
# include PETSC
if (PETSC_FOUND)
list(APPEND COMPILE_OPTIONS ${PETSC_CFLAGS})
include_directories(${PETSC_INCLUDE_DIRS})
set(LINK_FLAGS "${LINK_FLAGS} ${PETSC_LDFLAGS}")
list(APPEND LIBRARIES ${PETSC_LINK_LIBRARIES})
set(CMAKE_REQUIRED_FLAGS ${PETSC_CFLAGS})
set(CMAKE_REQUIRED_INCLUDES "${PETSC_INCLUDE_DIRS}")
endif()
# include Eigen
find_package (Eigen3 3.3 REQUIRED NO_MODULE)
# VTK library
