I _think_ you want:


project( component1 )
set( CMAKE_EXECUTABLE_OUTPUT_PATH "build/${project_name}" )
add_executable( component1 ${source_files} )

Is there a "master" cmakelists.txt within the myroot directory? Are  
you compiling all the components separately or through a master  
cmakelists.txt file?


For example if you have the following path: myroot/component1 and you  
create a build directory within that directory called BUILD so you  
have the path: myroot/component1/BUILD then run that bit of CMake code  
you will end up with executables in myroot/component1/BUILD/build/ 
component1


I think what you are looking for is:
SET (EXECUTABLE_OUTPUT_PATH
   ${PROJECT_BINARY_DIR}/${CMAKE_PROJECT_NAME}
   CACHE PATH
   "Single Directory for all Executables."
   )

this would put component1 executables into myroot/component1/Build/ 
component1/*
