[CMake] Adding external executable

[Manoj Vaghela]

Dear Eric,

Thanks for your reply.

When I am using INSTALL (FILES... ) for adding external executable to my
CMakeLists.txt file, it shows the executable file in the RPM archive. But
it's execute permission is lost. What should I have to do for that?

Also, ADD_EXECUTABLE( ... IMPORTED) did not work for me. I added this line
but when archive is created, it did not include my executable in it.

This is sample of my CMakeLists.txt
-----------------------------------------------

SET( CPACK_GENERATOR "RPM" )

##### MAIN EXE
SET( MAIN_EXE myExe)
ADD_EXECUTABLE(${MAIN_EXE} SOME_SOURCE_FILES )
SET( INSTALL_DIR "$ENV{HOME}/MANOJ" )
INSTALL( TARGETS ${MAIN_EXEC} DESTINATION ${INSTALL_DIR} )

##### EXTERNAL EXE
SET( EXTERNAL_EXE "/home/manoj/EXTERNAL/a.out.exe" )
SET( IMPORTED_LOCATION ${EXTERNAL_EXE} )
ADD_EXECUTABLE( ${EXTERNAL_EXE} IMPORTED) // This does not pack the
executable

#INSTALL( FILES ${EXTERNAL_EXE} DESTINATION ${INSTALL_DIR}) // This packs,
but permissions lost

##### EXTERNAL LIB
INSTALL( FILES EXTERNAL_LIB DESTINATION ${INSTALL_DIR} )

INCLUDE(CPack)

Can you please tell me what is the error in this file?
Thanks..
