If I understand you correctly, you want to check whether the 
FindQGLViewer found what it was looking for?

There should be no need to turn the file into a macro. Once you do

# Additional CMake modules for 3rd party library checks reside here
SET(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_admin")
FIND_PACKAGE(QGLViewer)

which executes the code in FindQGLViewer.cmake, you can do stuff like:

IF(QGLVIEWER_FOUND)
   MESSAGE(STATUS "QGLViewer found")
   ...
ENDIF(QGLVIEWER_FOUND)

in your CMakeLists file and use the variables set by the 
FindQGLViewer.cmake.

HTH, Mike
