LINK_FLAGS is a space-delimited string, so when the build path contains
spaces the linker map option is split into bogus arguments and the final
link fails:
clang++: error: no such file or directory:
'pro/KytyPS5/_Build/linux/kyty_emulator_clang_lld.map'
Move -Wl,-Map=<path> out of LINK_FLAGS into target_link_options, which
CMake passes to the linker as a single argument. This completes #26 for
the WIN32 OR LINUX branch (clang/gcc builds); the clang-cl branch was
already converted there.
