"cpuinfo" is a direct dependency of NNPack. It is installed via the NNPack's cmake script, but the version is not pinned. The "clog" dependency was recently removed from "cpuinfo" (pytorch/cpuinfo@3dc3103), which leads to issues when compiling TVM with support for NNPack. When building TVM with newly generated docker images and NNPack enabled, we run into the following cmake configuration error: ``` The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: NNPACK_CLOG_CONTRIB_LIB ``` This commit intends to fix this failure while also keeping compatibility with older versions of cpuinfo. It conditionally adds "clog" to the linker libs variable if it was found. Change-Id: I103f81b7ac75e9623ed808d240ce959749c13cf2
