Use ${PROJECT_NAME} instead of writing projectname multiple times (#134)

* Remove duplicate mentions of project name and replaced it with ${PROJECT_NAME} variable

Update CMakeLists.txt

* Added ${CMAKE_PROJECT_NAME}

* reverted usage of  to Greeter and ran fix-format

* Update test/CMakeLists.txt
