- Use -lopenblas instead of -llibopenblas, the former works on both MinGW and Cygwin while the latter only works on MinGW
- Replace ../../psopt-installer-master with actual location of patches in $PSOPT_BUILD_DIR
- Add PSOPT=../.. to final make install invocation, so Makefile_include.mk can be successfully located
