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

[emmmmmmmer]

I have install suitesparse by sudo apt-get install libsuitesparse-dev

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_CUDA_FLAGS="-arch=sm_61" ..
-- Symbol prefix:
CMake Error at applications/badslam/CMakeLists.txt:7 (find_package):
By not providing "FindSuiteSparse.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"SuiteSparse", but CMake did not find one.

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

SuiteSparseConfig.cmake
suitesparse-config.cmake

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

-- Configuring incomplete, errors occurred!
