title: How to know where a .f90 file installed?
body: <p>I installed a Linux software with compile, make install. Then I can't find a file called aaa.f90, the aaa.f90 is called by bbb.py, those two files are in my installation directory. How can I know where did it install from Makefile? I tried 'which aaa.f90', it's not work.</p>
  
  <p>I tried to read Makefile.am, Makefile.in, but it's very hard to understand.</p>
