How to add OpenXLSX to my project in c++? - c++

Question

I have a project and I want to use OpenXLSX as excel library. However, I can't add this to my project.
I move all OpenXLSX files into my project folder, it didn't work. Also moved them to my Desktop, it didn't work either.
Here is my CMakeList.txt file:
#cmake_minimum_required(VERSION 3.5)
#project(PCL_Visualizer LANGUAGES CXX)
#set(CMAKE_CXX_STANDARD 11)
#set(CMAKE_CXX_STANDARD_REQUIRED ON)
#add_executable(PCL_Visualizer main.cpp)
cmake_minimum_required(VERSION 3.5)
project(mainwindow)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
# init_qt: Let's do the CMake job for us
set(CMAKE_AUTOMOC ON) # For meta object compiler
set(CMAKE_AUTORCC ON) # Resource files
set(CMAKE_AUTOUIC ON) # UI files
# Find includes in corresponding build directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "/home/fatih/Desktop")
# Find the QtWidgets library
find_package(Qt5 REQUIRED Widgets)
find_package(VTK REQUIRED)
find_package(PCL 1.7.1 REQUIRED)
find_package(OpenXLSX REQUIRED)
# Fix a compilation bug under ubuntu 16.04 (Xenial)
#list(REMOVE_ITEM PCL_LIBRARIES "vtkproj4")
include_directories(${PCL_INCLUDE_DIRS})
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/OpenXLSX-master)
#include_directories(OpenXLSX-master/library/headers)
#include_directories(OpenXLSX-master/library/external/pugixml)
#include_directories(OpenXLSX-master/library/external/nowide/nowide)
#include_directories(OpenXLSX-master/library/external/zippy)
add_definitions(${PCL_DEFINITIONS})
set(project_SOURCES main.cpp mainwindow.cpp)
add_executable(${PROJECT_NAME} ${project_SOURCES} icons.qrc)
target_link_libraries(${PROJECT_NAME} ${PCL_LIBRARIES} Qt5::Widgets)
Everytime I try to cmake .. and make, i get this error.
Could not find a package configuration file provided by "OpenXLSX" with any
of the following names:
OpenXLSXConfig.cmake
openxlsx-config.cmake
Add the installation prefix of "OpenXLSX" to CMAKE_PREFIX_PATH or set
"OpenXLSX_DIR" to a directory containing one of the above files. If
"OpenXLSX" provides a separate development package or SDK, be sure it has
been installed.

Answer 1

I just add these commands to my CMakeList.txt and problem solved partially.
include_directories(/home/fatih/Desktop/OpenXLSX-master/library)
include_directories(/home/fatih/Desktop/OpenXLSX-master/build/library)
include_directories(/home/fatih/Desktop/OpenXLSX-master/library/headers)
link_directories(/home/fatih/Desktop/OpenXLSX-master/build/library)
link_directories(/home/fatih/Desktop/OpenXLSX-master/build/library/headers)
link_directories(/home/fatih/Desktop/OpenXLSX-master/library/headers)
target_link_libraries(${PROJECT_NAME} OpenXLSX VERSION 0.2.0 LANGUAGES CXX)
However, now I get different type of error.
/usr/bin/ld: cannot find -lOpenXLSX
/usr/bin/ld: cannot find -lVERSION
/usr/bin/ld: cannot find -l0.2.0
/usr/bin/ld: cannot find -lLANGUAGES
/usr/bin/ld: cannot find -lCXX
/usr/bin/ld: cannot find -lOpenXLSX
/usr/bin/ld: cannot find -lVERSION
/usr/bin/ld: cannot find -l0.2.0
/usr/bin/ld: cannot find -lLANGUAGES
/usr/bin/ld: cannot find -lCXX
Edit: I solved that problem too. If someone gets an error like this, I changed the target_link_library comment to this:
target_link_libraries(${PROJECT_NAME} /home/fatih/Desktop/OpenXLSX-master/build/output/libOpenXLSX-shared.so)
