I built Open3D from source into a /home/user/custom_location/Open3D/build
I have a project with a dependency on Open3D and a CMakeLists.txt like this:
cmake_minimum_required(VERSION 3.12)
project(graph_filter)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(CMAKE_CXX_EXTENSIONS OFF)
# Pybind11
find_package(pybind11 REQUIRED)
# OpenMP
find_package(OpenMP REQUIRED)
# Eigen
find_package(Eigen3 3.3 REQUIRED NO_MODULE)
# Open3D
list(APPEND CMAKE_INSTALL_PREFIX "~/libraries/")
find_package(Open3D HINTS ${CMAKE_INSTALL_PREFIX}/lib/CMake)
list(APPEND Open3D_LIBRARIES dl)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${Open3D_CXX_FLAGS}")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${Open3D_EXE_LINKER_FLAGS}")
include_directories(${Open3D_INCLUDE_DIRS})
link_directories(${Open3D_LIBRARY_DIRS})
pybind11_add_module(
graph_filter
wrapper.cpp
)
target_link_libraries(graph_filter PRIVATE ${Open3D_LIBRARIES} Eigen3::Eigen OpenMP::OpenMP_CXX)
How can I link it? When I run
INSTALL_DIR=/home/user/custom_location/Open3D/build
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=${INSTALL_DIR}```
I am getting:
Could NOT find Open3D (missing: Open3D_DIR)
fatal error: Open3D/Open3D.h: No such file or directory
2 | #include <Open3D/Open3D.h>
What is more confusing is the contents of Open3D/build folder after building from source.
I just want to resolve this dependency on Open3D. Thanks for any help!!!

I want to build a project which needs FLANN. When executing cmake, it shows
-- Checking for module 'flann'
-- Found flann, version 1.9.1
-- FLANN found (include: /usr/local/Cellar/flann/1.9.1_7/include, lib: flann;flann_cpp)
-- FLANN found (include: /usr/local/Cellar/flann/1.9.1_7/include, lib: flann;flann_cpp)
But I got ld: library not found for -lflann when executing make.

I have installed Intel opencl sdk for windows and opencl variable are added to the environment variables. I want to use this sdk with my Clion ide which I am unable to include it in my current project since it was CL/cl.hpp not found. How can add it to my project in Clion?
Cl/cl.hpp is located atC:\Program Files(x86)\IntelSWTools\OpenCL\sdk\include\CL
following is my CMakeLists.txt

You need to provide information about include directory for OpenCL headers like you provided for Boost headers. Also, you need to link OpenCL libraries with your target.
In your CMakeLists...
For include and link directories:
link_directories(${Boost_LIBRARY_DIRS} ${OpenCL_LIBRARY})
include_directories(${Boost_INCLUDE_DIRS} ${OpenCL_INCLUDE_DIRS})
For linking libraries:
set(LIBS ${LIBS} ${Boost_LIBRARIES} ${OpenCL_LIBRARY})
I want to build the following project: https://github.com/reo7sp/tgbot-cpp
I get these errors: https://imgur.com/S9kgWyv
Makefile part 1: https://imgur.com/O222bJR
Makefile part 2: https://imgur.com/i68QLdC
Now, I think that I need zlib, openssl and boost. Curl seems to be optional.
What is "threads"?
And what is the difference between ...LIBRARY_DEBUG and ...LIBRARY_RELEASE?
What doe LIB and SSL mean in the gui? These "libraries" are not mentioned in the makefile?
I am desperate for days now. Please, help me.

It turned out that I needed to set some system variables for OpenSSL, ZLib, Boost, curl. For Zlib just do the same procedure. drescherjm was a huge help. So thanks!

I'm trying to build a C++ application which uses the library libpamg0-dev.
I installed it with the following command on my elementaryOS VM.
apt-get install libpam0g-dev
When I try to compile the application, the compiler spits out the following errors:
undefined reference to `pam_start`
undefined reference to `pam_authenticate`
undefined reference to `pam_end`
My CMakeLists.txt looks like this:
cmake_minimum_required(VERSION 3.10)
project(application)
set(CMAKE_CXX_STANDARD 11)
INCLUDE_DIRECTORIES(/home/dnagl/dev/libs/restbed/distribution/include /usr/include/security)

target_link_libraries(application restbed)
Maybe one of you knows how to link the library in the right way.
I have found a nice solution with find_package option from CMake. CMake provides a way to find packages/libraries with specified FindModule.cmake file.
A really good news is that there are a lot of existing module files. You can use this version to find PAM package on Linux. Put it to cmake/modules/ in your project folder and update your CMakeLists.txt:
cmake_minimum_required(VERSION 3.10)
project(restbed)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)
# Notify CMake that we have module files to find packages/libs.
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/modules/")
find_package(PAM REQUIRED)
# Check if we found PAM.
if (NOT PAM_FOUND)
message(FATAL_ERROR "PAM library was not found.")
endif ()
# Source configuration.
include_directories(
${PAM_INCLUDE_DIR}
${CMAKE_BINARY_DIR}
${CMAKE_CURRENT_BINARY_DIR}
)
set(EXECUTABLE_NAME "application")
# Add sources to this project's executable.
add_executable(${EXECUTABLE_NAME}
"main.cpp"
"Utils/Json/Json.cpp"
"Utils/Json/Json.h"
"Utils/Stringhelper/Stringhelper.cpp"
"Utils/Stringhelper/Stringhelper.h"
"Utils/File/Filehelper.cpp"
"Utils/File/Filehelper.h"
"Utils/System/SystemHelper.cpp"
"Utils/System/SystemHelper.h"
"Controller/Info/InfoController.cpp"
"Controller/Info/InfoController.h"
"Rest/ResourceHandler/ResourceHandler.cpp"
"Rest/ResourceHandler/ResourceHandler.h"
"Controller/System/SystemController.cpp"
"Controller/System/SystemController.h"
"Rest/Log/RequestLogger.cpp"
"Rest/Log/RequestLogger.h"
"Controller/Authentication/AuthenticationController.cpp"
"Controller/Authentication/AuthenticationController.h"
"Controller/Log/LogController.cpp"
"Controller/Log/LogController.h"
)
target_link_libraries(${EXECUTABLE_NAME}
${PAM_LIBRARIES}
)
set_target_properties(${EXECUTABLE_NAME} PROPERTIES LINKER_LANGUAGE CXX)
Hope this helps!
