Blaze 3.3 already defines the function l1Norm
The library blaze 3.3 contains a file 'blaze/math/expressions/DVecNormExpr.h' that defines a function:
template<class VT, bool TF> decltype(auto) blaze::l1Norm(const blaze::DenseVector<VT, TF>&)
In tmpc, the file BlazeKernel redefines the function l1Norm
, which generates a compiler error.
