build: common CMakeLists to rule them all (#6)

With these changes the entire package (the min useful sub-packages) can
be built as:

```
cmake -S esi-opticks -B build
cmake --build build
```

-Opticks CMake Conventions (STILL APPLY)
-=========================================
-
-1. project names are the same as the library targets they generate 
-2. project names are CamelCased, project directory names are lowercase
-3. lowercased project names match the names of their directories
-4. every CMake project command should be followed by "include(OpticksBuildOptions)"
-5. the name of every project should be set via a "name" variable : this is used within
-   the OpticksBuildOptions to set the install location of headers as include/${name}
-
-For example a project called DemoProj would be setup in demoproj subdirectory with
-a CMakeLists.txt file starting::
-
-    cmake_minimum_required(VERSION 3.5 FATAL_ERROR)
-    set(name DemoProj)
-    project(${name} VERSION 0.1.0)
-    include(OpticksBuildOptions)
-
-
-DECISION TO HALT ATTEMPTS TO GET INTEGRATED BUILD OPERATIONAL AGAIN
----------------------------------------------------------------------
-
-Because it doesnt add enough value for the effort, instead 
-just use proj-by-proj integrated at bash level with om.bash, 
-see om-install
-
-This Integrated Build  : ON HOLD
-------------------------------------
-
-For this integrated build, find_package is redefined by the below
-macro to skip packages corresponding to the below SUBDIRS as they have directly 
-been built already within the single CMake context and hence do not need to be found.
-
-This structure allows the proj-by-proj building and integrated building to otherwise
-be identical.
-
-bcm_ignore_package
-~~~~~~~~~~~~~~~~~~~
-
-Incase decide to try again with integrated build, try 
-out the bcm_ignore_package approach:
