How to link library with suffix d for debug?

zhang-qiang-github · October 28, 2021, 12:12pm

I want to use a third package (VTK) in my project, and the folder is:

Thirdparty
    VTK
        bin
            Debug
                vtkCommonCore-9.0d.dll
                ...
            Release
                vtkCommonCore-9.0.dll
                ...
        include
                xxx
                ...
        lib
            Debug
                vtkCommonCore-9.0d.lib
                ...
            Release
                vtkCommonCore-9.0.dll
                ...

In my CMakeLists.txt:

set(VTI_DIR "xxx/Thirdparty/VTK")
include_directories(
    ${VTK_DIR}/include
)
target_link_libraries(Pro
    vtkCommonCore-9.0
    ....
)

If I use target_link_libraries(Pro vtkCommonCore-9.0d ....) , the code would be ok for debug but wrong for release.
If I use target_link_libraries(Pro vtkCommonCore-9.0 ....) , the code would be ok for release but wrong for debug.

One solution is:

target_link_libraries(Pro
    debug vtkCommonCore-9.0d
    optimized vtkCommonCore-9.0
    ....
)

But, it seem to be inconvenient.

Is there any method which is more convenient?

Yes. Use find_package(VTK) and link to VTK::CommonCore instead.

zhang-qiang-github · October 29, 2021, 1:28am

If I want to use fidn_package(VTK), I need to compile vtk in my computer. But, I don’t want to build vtk in my computer, and I just want to use vtk by bin/lib/include.

ben.boeckel · October 29, 2021, 12:16pm

How are you going to use it if you don’t compile it? Where does libvtkCommonCore-9.0.lib come from if you haven’t built it?

zhang-qiang-github · October 30, 2021, 1:46pm

I can build vtk in one compute, and install vtk. Thus, I can obtain the dll/lib/include files.

Then, I copy thus files to another computer. In this new computer, the vtk is not built, and the find_package will fail.

I want to use vtk by only dll/lib, rather that to build it.

Why do you not pack the hole installation packages of vtk?

As stated above, you should copy the whole install tree. That will come with what you need to find_package(VTK). This includes the vtk_module_autoinit command you’ll need to use if you use any object factories (commonly, rendering or MPI support).

zhang-qiang-github · November 1, 2021, 2:47am

Yes, I have copied the whole install tree. Now, the folder is:

Thirdparty
    VTK
        bin
            Debug
                vtkCommonCore-9.0d.dll
                ...
            Release
                vtkCommonCore-9.0.dll
                ...
        include
                xxx
                ...
        lib
            Debug
                cmake
                    vtk-9.0
                        patches
                        Finddouble-comversion.cmake
                        ....
                        vtk-config.cmake
                        ...
                        VTK-targets-debug.cmake
                        ...
                vtkCommonCore-9.0d.lib
                ...
            Release
                cmake
                    vtk-9.0
                        patches
                        Finddouble-comversion.cmake
                        ....
                        vtk-config.cmake
                        ...
                        VTK-targets-release.cmake
                        ...
                vtkCommonCore-9.0.dll
                ...

But, if I use find_package(VTK) as:

set(VTK_DIR "${CMAKE_CURRENT_SOURCE_DIR}/Thirdparty/VTK")
find_package(VTK)

The cmake will report :

By not providing "FIndVTK.cmake" in CMAKE_MODULE_PATH this project has asked CMAke to find a package configuration file provided by "VTK", but CMAke did not find one.

Could not find a package configuration file provided by "VTK" with any of the following names:

VTKConfig.cmake
vtk-config.cmake

Add the installation prefix of "VTK" to CMAKE_PREFIX_PATH or set "VTK_DIR" to a directory containing one of the above files. If "VTK" provided a separate development package or SDK, be sure it  has been installed.

If my following cmake file is wrong?

set(VTK_DIR "${CMAKE_CURRENT_SOURCE_DIR}/Thirdparty/VTK")
find_package(VTK)

How can I implement my cmake file to make find_package work?

ben.boeckel · November 1, 2021, 11:03am

You can either set CMAKE_PREFIX_PATH to the install root of VTK or VTK_DIR to the directory that contains vtk-config.cmake.

zhang-qiang-github · November 1, 2021, 12:57pm

There are two paths contains vtk-config.cmake.

Thirdparty/VTK/lib/Debug/cmake/vtk-9.0
Thirdparty/VTK/lib/Release/cmake/vtk-9.0

Whick path should be VTK_DIR?

ben.boeckel · November 1, 2021, 1:26pm

How did you get such a setup? The CMake files should never be under a config-specific location unless you specified that manually. If you want a single install prefix with both, you’ll need a single CMake package directory which knows about both.

zhang-qiang-github · November 1, 2021, 2:05pm

Yes, I manually copy the dll/lib/include files to a config-specific location. The reason is that I want to include Debug/Release/RelWithDebInfo files.

If I do not copy dll/lib/include files to a config-specific location manually, I can distinguish the debug/release by suffix. But, how can I distinguish lib of release and RelWithDebInfo?

ben.boeckel · November 1, 2021, 2:55pm

Right now, VTK doesn’t have a different suffix for release and relwithdebinfo built-in. You can pass -DCMAKE_RELWITHDEBINFO_POSTFIX=rd to the configure to make a different suffixes for that configuration. Then you should be able to have then entire setup in a unified config-less install tree.

zhang-qiang-github · November 2, 2021, 7:30am

My folder is:

Thirdparty
    x64
        VTK
            bin
            include
            lib
                cmake
                    vtk-9.0
                        vtk-config.cmake
                        ...

And My Cmakelists.txt is:

set(VTK_DIR "${CMAKE_CURRENT_SOURCE_DIR}/Thirdparty/$(PlatformName)/VTK/lib/cmake/vtk-9.0")
find_package(VTK REQUIRED)

But, it still reported:

By not providing "FIndVTK.cmake" in CMAKE_MODULE_PATH this project has asked CMAke to find a package configuration file provided by "VTK", but CMAke did not find one.

Could not find a package configuration file provided by "VTK" with any of the following names:

VTKConfig.cmake
vtk-config.cmake

Add the installation prefix of "VTK" to CMAKE_PREFIX_PATH or set "VTK_DIR" to a directory containing one of the above files. If "VTK" provided a separate development package or SDK, be sure it  has been installed.

Then, I print the VTK_DIR, it shows:

Project/Thirdparty/$(PlatformName)/VTK/lib/cmake/vtk-9.0

Is there any wrong with my VTK_DIR by: set(VTK_DIR "${CMAKE_CURRENT_SOURCE_DIR}/Thirdparty/$(PlatformName)/VTK/lib/cmake/vtk-9.0")?

But, the following is OK:

set(VTK_DIR "${CMAKE_CURRENT_SOURCE_DIR}/Thirdparty/x64/VTK/lib/cmake/vtk-9.0")

ben.boeckel · November 2, 2021, 11:31am

CMake will take this literally, so it will never see x64. You’ll need to compute this based on whatever information you have and set a CMake variable appropriately.
