Hello, All!
My name is Navadvipa Chandra das.
My language is Russian. I use translate dot yandex dot ru.
Windows 11 64-bit operating system
CMake - cmake-3.31.4-windows-x86\_64
There is a CopperSpice library. I’m adding my NNPrabhupada library there.

File
D:\CopperSpice\Source\src\Prabhupada\CMakeLists.txt
I created a similar file
D:\CopperSpice\Source\src\svg\CMakeLists.txt
Fixed one line in the file
D:\CopperSpice\Source\CMakeLists.txt
set(CS\_OPTIONAL\_COMPONENTS Gui Multimedia Network OpenGL Sql Svg Vulkan WebKit XmlPatterns Prabhupada)
I install CopperSpice
CopperSpice configured to run on: Windows 64 bit, Release Mode
CopperSpice will be built in: D:/CopperSpice/Release/Build
CopperSpice will be installed in: D:/CopperSpice/Release/Lib
But I get a problem.
This file has been installed
D:\CopperSpice\Release\Lib\lib\CsSvg2.0.lib
But there is no expected file
D:\CopperSpice\Release\Lib\lib\NNPrabhupada2.0.lib
There is a file
D:\CopperSpice\Release\Lib\bin\CsSvg2.0.dll
And there is also a file
D:\CopperSpice\Release\Lib\bin\NNPrabhupada2.0.dll
It’s interesting to see the file
D:\CopperSpice\Release\Build.ninja.log

That is, the library name “NNPrabhupada2.0.lib” occurs twice, and the library name “CsSvg2.0.lib” occurs only once.
I want to get the NNPrabhupada2.0.lib file, but it’s not there. Riddle.
Would anyone be not lazy to solve such a problem? I’ve reached a dead end. I do not know how to debug CMake. I don’t really know CMake, I just do it according to the pattern.
Of course, installing CopperSpice itself is also not an easy task.
You can read a bit about how I installed CopperSpice here.:

The description is in Russian, but now the translation of the text is a bit of a problem.
With great hope for help, Navadvipa Chandra das.

Hello, All!
It turned out that the problem was not CMake, but that the classes and functions C++ were not specifically cross-linked to be placed in the library. Since the library eventually had 0 classes and 0 functions, the lib file was not created either.
With regards, Navadvipa Chandra das.
