Issue with Pointing to an Alternative Location for Ruby

[stephen-ritter]

Basically the same issue as #40 but for the Ruby binary. On my system it is located here:

[root@dd9133d54e47 bin]# which ruby
/usr/local/bin/ruby

GMSEC_API/ruby/gmsec5/MakeRuby

Lines 18 to 22 in ac7d45e

	ifeq ($(findstring macosx,$(GMSEC_PLATFORM)), macosx)
	RUBY = /usr/local/opt/ruby/bin/ruby
	else
	RUBY = /usr/bin/ruby
	endif

The /usr/bin/ruby is the standard location on Ubuntu 20.04 and RHEL8 systems. If an alternative is needed, then you have two choices:

1. Edit the Makefile
2. Run make and override the variable

Regarding the latter option, something like this:

$ make RUBY=/usr/local/bin/ruby

If you prefer something more elaborate to be included with the distribution (say for GMSEC API 5.3), then you will need to contact the curators at gmsec-support@lists.nasa.gov.

Again thanks for the tip! That worked. It has been a while since I have messed with Makefiles. I think something that would be nice on this front is adding more instructions on how to build the GMSEC_API, because if you are on a system where you had to build dependencies from source (let's say running yum/dnf/microdnf install gets you an older version of the required package that won't work) you can't always rely on the standard locations for these files.
