To build on Mac m1 #468

Closed rvjansen closed 11 months ago

rvjansen commented 2 years ago

The clang compiler on the M1 macs does not like -march=native. This can be remedied by a 

set(PRIVATE_HELIB_CXX_FLAGS "-mcpu=lightning")

in the CmakeLists.txt file. This issue documents the change.

this helped me, but instead of using "mpcpu" I used 

set(PRIVATE_HELIB_CXX_FLAGS "-mcpu=apple-m1")
