Hello Jupiter,
can you post the error message here? I wasn't aware that install(FILES ...) did
any checking besides comparing the dates and overwriting if the file to be
installed is newer.
Also, you misunderstood what Petr meant. You need to escape the quotes in the
install(CODE "...") call, because you're effectively writing a string to a
file, i.e.:
install(CODE "
if (NOT EXISTS \"${destination}/myfile.txt\")
install(FILES \"${source}/myfile.txt\" DESTINATION ${destination})
endif()
")
BUT: using install inside an install command smells like problems, so you
better use the file(INSTALL...) directive, anyway:
install(CODE "
if (NOT EXISTS \"${destination}/myfile.txt\")
file(INSTALL \"${source}/myfile.txt\" DESTINATION \"${destination}\")
endif()
")
using the SCRIPT signature expects a cmake script file that will be included in
the cmake_install.cmake script file. This means you would need to configure
your paths in your cmakelists file
configure_file(myfile_install.cmake.in myfile_install.cmake)
install(SCRIPT myfile_install.cmake)
and in myfile_install.cmake.in you'd put
if(NOT EXISTS "${destination}/myfile.txt")
file(INSTALL "${source}/myfile.txt" DESTINATION "${destination}")
endif()
Hope that helps,
Andreas
