I am porting a C++ project I have been working on for 2 years, to Windows, and I am facing this link issue, that I haven't seen on any google-referenced posts... :/
It is a CMake-generated project, and I get these CMake entries set by default to "\machine:x64"
CMAKE_EXE_LINKER_FLAGS
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS
I tried removing the flag, which has no effect on any of the 3 last entries, but CMAKE_EXE_LINKER_FLAGS without this value gives me about 85 unresolved externals spread in my libraries.
ALL my projects / project dependencies are compiled with MSVC2015 in x64.
Linking fails both in debug & release mode (not that it matters..)
I should also probably mention that I have 6 projects in this solution, 4 libraries, 2 executables. 4 of these projects are compiling fine (1 executable & 4 libs), only the 2 last ones are failing (with the same link error for both).
The only difference in terms of dependencies are a dependency to the Point Cloud Library (pcl), and to Qt5 (Core GUI, XML, and OpenGL)
Did anyone already encountered this specific linker error?
Hope you can help =)
EDIT: Here are the 2 main CMakelists files (the one at the root of the project and the one that compiles both failing projects). I removed everything that didn't seem pertinent for this issue.

I am newbie on CMAKE. I am trying to make "fat executable file".
The term, fat executeable file, I mentioned, is a executable binary file which contains all shared libraries and can be just run in another environment.
Example (Trouble Situation)
There is ComputerA which is a computer that I used for developing. There is GCC, Boost libraries, librados etc.
And there is ComputerB which is a computer that I wanted to execute the binary that I built.
* Of course, Both Computer A and B have some conditions. Same Intel CPU Arch. (i7), Same CentOS.
I built binary file in ComputerA using CMAKE with this command, cmake .. && make. And I copied this file to ComputerB and executed.
When I execute the copied binary file in Computer B, it said like below.
[root#ComputerB ~]# ./binaryFile 123.123.123.123
./binaryFile: error while loading shared libraries: libboost_json.so.1.80.0: cannot open shared object file: No such file or directory
I understand what this error message say. There is no shared library which it needed. So, what I want to ask in this community is, What is CMAKE Command for containing shared libraries.
Similar thing :: fat JAR
The reason, why I called "fat executable file", is that there is a word "fat JAR" in Java. I am not familiar with Java. But it is commonly used word in Java community.
My CMAKE File
It contains some libraries like Boost, Rados, RBD etc. (There will be more according to progress of developing)

I'm attempting to alter my CmakeLists.txt file for my currently working MacOSX version of my OpenGL engine, so that it will compile and run on windows. I'm positive that I'm doing something wrong in the way I'm writing my Cmakelists.txt and would like some help correcting it.
Have already tried a multitude of different tutorials and examples found online. The problem most likely lies in how I'm trying to link dll files but I'm unsure of what I'm doing wrong.

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})
For the past few days I've been searching everywhere and can't seem to fix this problem or maybe I just didn't understand some answers.
I have an application (a game to be precise) built with SFML that I managed to compile on Linux with 2.4.2 version. I want to migrate to 2.5.1 and be able to compile on Windows so I changed the CMakeLists.txt file to this:

The cmake works and generates the VS solution, that I can build with msbuild (note that I don't want to launch Visual Studio, but only use msbuild). But once I try to run it, it asks for dlls and I don't want that.
I thought that would be solved by linking statically (I don't know much about static or dynamic linking) but it still asks for them.
In this link they say that we don't need to include the ${SFML_INCLUDE_DIR} and ${SFML_LIBRARIES} anymore: https://en.sfml-dev.org/forums/index.php?topic=24070.0
How can I avoid that? I want to be completely independant from DLL's or at least be able to include the bin directory installed from SFML compiled and installed binaries (that I compiled, not the precompiled).
Thank you.
I've written a small programm for evaluating sientific data (3D surface mesh). I do all the geometric calculations with functions provided by the vtk library. The vtkBooleanOperationPolyDataFilter is no robust and crashes randomly. So i decided to performe the boolean operations with functions of the cgal library (tested with some sample data -> no stability problems).
Now I want to merge this two projects together.
The vtk project CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
PROJECT(calcporosity)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
add_executable(calcporosity MACOSX_BUNDLE calcporosity)
if(VTK_LIBRARIES)
target_link_libraries(calcporosity ${VTK_LIBRARIES})
else()
target_link_libraries(calcporosity vtkHybrid vtkWidgets)
endif()
The cgal project CMakeLists.txt:
project( cgal_test )
cmake_minimum_required(VERSION 2.6.2)
if("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" VERSION_GREATER
2.6) if("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}.${CMAKE_PATCH_VERSION}"
VERSION_GREATER 2.8.3)
cmake_policy(VERSION 2.8.4) else()
cmake_policy(VERSION 2.6) endif() endif()
find_package(CGAL QUIET COMPONENTS Core )
if ( CGAL_FOUND )
include( ${CGAL_USE_FILE} )
include( CGAL_CreateSingleSourceCGALProgram )

include_directories (BEFORE "include")
create_single_source_cgal_program( "cgaltest.cpp" ) else()
message(STATUS "This program requires the CGAL library, and will not be compiled.")
endif()
I tried to merge this to files but I've failed. Could some give me a hint how to create a proper CMakeLists.txt for a project which utilizes both libraries.
Thanks in advance and best regards!
P.s.: I'm working on a Windows plattform
Basically what needs to happen is that you need to provide include directories and link libraries from both of your dependencies to your executable.
cmake_minimum_required(VERSION 2.8.4)
project( cgal_vtk_test )
# Find CGAL
find_package(CGAL REQUIRED COMPONENTS Core) # If the dependency is required, use REQUIRED option - if it's not found CMake will issue an error
include( ${CGAL_USE_FILE} )
# Find VTK
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
# Setup your executable
include_directories (BEFORE "../../include")
include_directories (BEFORE "include")
include( CGAL_CreateSingleSourceCGALProgram )
create_single_source_cgal_program( "cgal_vtk_test.cpp" ) # This will create an executable target with name 'cgal_vtk_test'
# Add VTK link libraries to your executable target
target_link_libraries(cgal_vtk_test ${VTK_LIBRARIES})
