If you use Cygwin tools, you shouldn't use paths like
"/cygdrive/c/cygwin/lib". The way to refer to
that directory is /lib (unless your Cygwin is installed somewhere
other than C:\cygwin).

/lib is not really for headers. It mostly contains binaries. A
canonical place for a header-only library would be
/usr/local/include/eigen
Doesn't eigen supply a makefile with an "install" target?
