installation on Mac

[hfattahi]

I had to slightly change the Cmake command from:

CXX=clang++ cmake -DCMAKE_INSTALL_PREFIX=../install ../src/fringe

To the following to install the package on my Mac:

CXX=clang++ cmake -DCMAKE_FIND_FRAMEWORK=NEVER -DCMAKE_INSTALL_PREFIX=../install ../src/fringe
Before issuing a PR I wanted to make sure if others have experienced this?

Just my 2¢, but I always use this option on macOS so my cmake PR recommends it in the isce2 readme. https://github.com/isce-framework/isce2/pull/136/files#diff-04c6e90faac2675aa89e2176d2eec7d8R324-R329

Yep. Need it to circumvent the default framework.

I got the cmake -DCMAKE_FIND_FRAMEWORK=NEVER -DCMAKE_INSTALL_PREFIX=../install ../src/fringe to work on my Mac, but I am having trouble with it not finding the mpi.h file on build.

In case it matters, this is what I have for MacPorts:

port select mpi
Available versions for mpi:
	none
	openmpi-devel-mp-fortran
	openmpi-gcc7-fortran (active)
	openmpi-mp-fortran
