[BUG] CMake error: add_library cannot create ALIAS target "cutlass_lib" because target "cutlass_library" does not already exist.

[lahwaacz]

Having installed cutlass 3.3.0 and using find_package(cutlass) in a project, I get this error:

CMake Error at /usr/lib/cmake/NvidiaCutlass/NvidiaCutlassConfig.cmake:12 (add_library):
  add_library cannot create ALIAS target "cutlass_lib" because target
  "cutlass_library" does not already exist.
Call Stack (most recent call first):
  src/CMakeLists.txt:44 (find_package)

It seems that cutlass_library is not defined anywhere?

Thanks for reporting this, @lahwaacz! Can you provide your CMake command/arguments? This line of code should create the cutlass_library target.

@d-k-b cutlass was configured like this:

cmake -S . -B build -G Ninja \
    -DCMAKE_BUILD_TYPE=None \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DCUTLASS_NVCC_ARCHS="60;61;70;75;80;86;89" \
    -DCUTLASS_ENABLE_GTEST_UNIT_TESTS=OFF \
    -DCUTLASS_ENABLE_TESTS=OFF \
    -DCUTLASS_ENABLE_CUBLAS=ON \
    -DCUTLASS_ENABLE_CUDNN=ON \
    -DCUTLASS_ENABLE_EXAMPLES=OFF \
    -DCUTLASS_INSTALL_TESTS=OFF \
    -DCUTLASS_UNITY_BUILD_ENABLED=ON

Thanks, I found the issue and am working on a fix. In the meantime, you can just remove that offending line of code from NvidiaCutlassConfig.cmake and that should unblock you.

Resolved with v3.4 release
