If he's trying to compile an external package from within cmake, I usually 
do this by adding add_custom_command(OUTPUT ${srcdir}/Makefile COMMAND 
${srcdir}/configure ...) to the CMakeFile.txt, create another one to invoke 
'make' dependent of the ${srcdir}/Makefile of the last add_custom_command, 
and finally use add_custom_target to create a target that initiates the 
whole shebang, having as depedency the output of the last 
add_custom_command.
