gcc says:
-pthread
Adds support for multithreading with the pthreads library. This
option sets flags for both the preprocessor and linker.
So it may work to only use it during linking but this may cause subtle failure
on some platforms.
When writing FindThreads.cmake, it would be better to really rewrite it and
use the common naming standards for cmake modules.
