This makes some sense. Thank you. As for this:
def detect_modules(self):
# Ensure that /usr/local is always used
add_dir_to_list(self.compiler.library_dirs, '/usr/local/lib')
add_dir_to_list(self.compiler.include_dirs, '/usr/local/
include')
it looks like a recipe for a disaster when cross compiling:
cc1: warning: include location "/usr/local/include" is unsafe for
cross-compilation
