Why are just some Ogre3D dependencies building for Release when the rest builds for Debug?

Question

I am building for Ogre version 14.1.1 Github link https://github.com/OGRECave/ogre Windows 10 Renderer d3d11

I am having trouble with these 2 dependencies: OgreBullet, Assimp

I have followed the official building tutorial, AND followed forum discussions for any fixes. Build tutorial link: https://ogrecave.github.io/ogre/api/latest/building-ogre.html

These are the steps I am doing:

1. Downloaded the repository and extracted it.
2. I made a folder /build/debug inside it.
3. then after go to cmd prompt from the folder path and initiate a variable. This is because of the dependencies are built during the configure stage of CMake, we must specify the desired CMAKE_BUILD_TYPE via command-line. Changing the value in the CMake GUI will have no effect. set CMAKE_BUILD_TYPE=Debug
4. then run cmake-gui.exe -DCMAKE_BUILD-TYPE=Debug in cmd prompt
5. then after CMAKE interface open, I clicked BrowseSource to set the downloaded repository folder.
6. in BrowseBuild I set the /build/debug folder
7. I hit configure button, then with given settings (for debug build) I generate, if no errors occurred.
8. Then I open the generated solution in Visual Studio 2022.
9. I build for the predefined target "ALL_BUILD"

I was already able to build for debug once such that Assimp was working. I worked with Assimp in Ogre. But now I am trying to build OgreBullet also, and now both these dependencies fail to build in debug.

the dependencies are built during configure . Here is my outputs

Answer 1

Visual Studio generated project's will require you to select your build type from it's four defaults Release, Debug, MinSizeRel & RelWithDebInfo) even when the project is generated with CMake. Having generated your visual studio project knowing that the build has failed is now it's own issue. You haven't mentioned the issue but I assume you are facing linking errors because in CMake you can see that:

BULLET_SOFTBODY_LIBRARY=C:/....
BULLET_SOFTBODY_LBRARY_DEBUG=BULLET_SOFTBODY_LBRARY_DEBUG-NOTFOUND

Suggesting you don't have the debug libraries for this bullet library. So if you attempt to build it, it won't have the debug library to link to. If the library does exist, make sure to set the CMake variable to the location of that library. But if that is not your issue, then posting your error message will be useful.
