Well, the libs are located in ...
Specifically, boost_thread is named libboost_thread_win32-mt.a

Maybe cmake looks for a different name with different conventions. You
may try to create a symlink to this file and name it
libboost_thread-mt.a, or libboost_thread.a. Also, cmake may be looking
for a shared lib, as libboost_thread is usually linked as shared.

If you link to the boost_thread static lib in mingw-cross-env, you'll
have to define -DBOOST_THREAD_USE_LIB while building your app.
Otherwise, thread local storage cleanup may cause linker errors or
even runtime problems.
