Check if a library is successfully installed through make install - installation

Question

I tried to install a library (RNNoise) on Cygwin with ./autogen.s - ./configure - make - make install.
Below is the result I got:
User#LAPTOP-R9ABJF4O /cygdrive/c/Windows/System32/rnnoise
$ ./autogen.sh
Updating build configuration files for rnnoise, please wait....

It seems that everything works well. However, I couldn't find the library (rnnoise). I searched through pip list and imp.find_module('rnnoise').
Is the library installed successfully? How do I know the name or path of the library?
