CI build improvement.

I couldn't figure out how to source scripts in the gitlab ci yaml file
so I had to create a "do_build" script which does everything.

	modified:   .gitlab-ci.yml
	new file:   bin/do_build

.gitlab-ci.yml

 image: whit2333/dd4hep-base:latest
 
-stages:
-  - build
-  - test
+before_script:
+  - pwd
+  - ls -lrth /usr/local/bin
 
-test:
-  stage: test
-  script: echo "Running tests"

-build:
-  stage: build
+# Try to compile our sample hello world app
+compile:
+  image: whit2333/dd4hep-base:latest
   script:
-    - mkdir install
-    - mkdir build
-    - cd build
-    - cmake .. -DCMAKE_INSTALL_PREFIX=../install
-    - make -j4 install
