I reworked the MIDAS Makefile to simplify things and to remove redundancy with functions 
provided by cmake.

When you say "make", the list of options is printed.

The first and main options are "make cmake" and "make cclean" to run the cmake build.

This is my recommended way to build midas - the output of "make cmake" was tuned to provide 
the information need to debug build problems (all compiler commands, command line switches 
and file paths are reported). (normal "cmake VERBOSE=1" is tuned for debugging of cmake and 
for maximum obfuscation of problems building the actual project).

Build options are implemented through cmake variables:

options that can be added to "make cmake":
      NO_LOCAL_ROUTINES=1 NO_CURL=1
      NO_ROOT=1 NO_ODBC=1 NO_SQLITE=1 NO_MYSQL=1 NO_SSL=1 NO_MBEDTLS=1
      NO_EXPORT_COMPILE_COMMANDS=1

for example "make cmake NO_ROOT=1" to disable auto-detection of ROOT.

Two more make targets create reduced builds of midas:

"make mini" builds a subset of midas suitable for building frontend programs. Big programs 
like mlogger and mhttpd are excluded, optional components like CURL or SQLITE are not needed.

"make remoteonly" builds a subset of midas suitable for building remotely connected 
frontends. Big parts of midas are excluded, many system-dependent functions are excluded, 
etc. This is intended for embedded applications, such as fpga, uclinux, etc.

But wait, there is more. Here is the full list:

Usage:

   make cmake     --- full build of midas
   make cclean    --- remove everything build by make cmake

   options that can be added to "make cmake":
      NO_LOCAL_ROUTINES=1 NO_CURL=1
      NO_ROOT=1 NO_ODBC=1 NO_SQLITE=1 NO_MYSQL=1 NO_SSL=1 NO_MBEDTLS=1
      NO_EXPORT_COMPILE_COMMANDS=1

   make dox       --- run doxygen, results are in ./html/index.html
   make cleandox  --- remove doxygen output

   make htmllint  --- run html check on resources/*.html

   make test      --- run midas self test

   make mbedtls   --- enable mhttpd support for https via the mbedtls https library
   make update_mbedtls --- update mbedtls to latest version

port 8443

   make mini      --- minimal build, results are in linux/{bin,lib}

   make linuxarm  --- minimal ARM cross-build, results are in linux-arm/{bin,lib}
   make cleanarm  --- remove everything built by make linuxarm

   make clean     --- run all 'clean' commands
