Use static buffer for module file name. According to the msdn examle the return value of getmodulefilename should be used to indicate success and not the size. And according to comments on that function on Windows 8.1 it does not return the needed size. So better be more robust and just use max_path as a limit.

# - Try to find PolarSSL

# Find the include directories
find_path(POLARSSL_INCLUDE_DIR NAMES polarssl/ssl.h)

find_library(POLARSSL_LIBRARIES NAMES polarssl)

include(FindPackageHandleStandardArgs)

find_package_handle_standard_args(POLARSSL
    REQUIRED_VARS POLARSSL_INCLUDE_DIR POLARSSL_LIBRARIES
)
