Hello
when i use cmake to complie my project,it have complie successfully,but when i got the link stage
but i got the probelm like this
ld: not found. -lcusolver: No file or directory
ld: Not found -lcublas: No file or directory
ld: Not found -lcufft: No file or directory
when i add the libs in the shell path,this time it doesn’t works
it seems that i need add the libcusolver.so,libcubals.so,libcufft.so in the CmakeLists.txt,i know i can add this by -L/path/to/libraries/…,however how can i add it in the cmakeLists.txt
–best wishes

Are you using `enable_language(CUDA)` or `find_package(CUDA)`? The latter is deprecated and you should use the CUDA language instead. I think some of this comes from `CUDAToolkit` though?

All these libraries have target representations provided by the `find_package(CUDAToolkit)` module.
You would link to the `CUDA::cusolver` target which knows where the actual library is on disk.

i use the hpc\_sdk,i can find the cusolver.so,cublas.so,cufft.so,but i can’t install the CUDAToolKit,so could tell how to add the shared time library in the project

`find_package(CUDAToolkit)` is aware of the hpc sdk layout and will find the components CUDA toolkit components inside of it.
Edit: You will want to use the newest version of CMake possible ( at a minimum 3.21 ) to get HPC SDK support from `find_package(CUDAToolkit)`.

If for some reason you can’t upgrade CMake, the HPC SDK also ships with the NVHPC module which will bring in support for these libraries.
That can be used like:
```cmake
project(helloworld CXX)
set(NVHPC_CUDA_VERSION 11.0)
find_package(NVHPC REQUIRED COMPONENTS MATH)
add_executable(helloworld "helloworld.cpp")
target_link_libraries(helloworld PRIVATE NVHPC::MATH)
```
The `NVHPC::MATH` target will ensure you link to cublas, cusolver, curand, cusparse, etc.
