Compiler error:

icx: error: cannot specify '-Fobin\rng\CMakeFiles\onemkl_rng.dir\rng_loader.cpp.obj' when compiling multiple source files

Reason is

oneMath/CMakeLists.txt

Line 215 in c255b1b

string(REPLACE "/MD" "" ${flag_var} "${${flag_var}}")

It replaces the "/MDd" used by default for debug builds with "d" which is then mistaken as 2nd input source.
