# blspy comes as a stand-alone extension module that's placed directly
|
# in site-packages.
|
#
|
# On macOS and Linux, it is linked against the GMP library, whose shared
|
# library is stored in blspy.libs and .dylibsblspy, respectively. As this
|
# is a linked dependency, it is collected properly by PyInstaller and
|
# no further work is needed.
|
#
|
# On Windows, however, the blspy extension is linked against MPIR library,
|
# whose DLLs are placed directly into site-packages. The mpir.dll is
|
# linked dependency and is picked up automatically, but it in turn
|
# dynamically loads CPU-specific backends that are named mpir_*.dll.
|
# We need to colllect these manually.
