CMake project configuration for external projects

S-01730

As a ExSeisDat Developer I want to add a CMake project configuration script to make adding ExSeisDat to external (CMake-based) projects easier.

PreDev Notes:

A project configuration script can save information like the compiler and flags used during compilation, along with definitions used, libraries linked, and installation directories. This information can then be accessed from a CMake script using the find_package command.

See tutorials on making a projectconfig.cmake file:

Success Criteria:

A CMake configure script for an external project using ExSeisDat can be written (assuming exseisdat is built and installed somewhere findable):

cmake_minimum_required(VERSION 3.5.2)
find_package(exseisdat REQUIRED)
add_executable(my_executable my_executable.cc)
target_link_libraries(my_executable exseisdat)
