Because libclc-remangler commands executed in cmake use
libclc::libclc-remangler
, builds whereCMAKE_CROSSCOMPILING=ON
do not work correctly since cmake assumes the target is not executable on the host machine.This change modifies the custom commands to use the cache variable
LIBCLC_REMANGLER_PATH
instead, where this variable is set in a similar way as llvm tools such asllvm-config
by callingcompile_native_tool
.
