This is the way I like it: - Only call fpc on hwengine.pas, let compiler rule the dependencies - Make hwengine.pas depend on all other source files, so 'make' always calls fpc

file(GLOB luafiles *.lua)
file(GLOB cfgfiles *.cfg)

install(FILES
    ${luafiles}
    ${cfgfiles}
    DESTINATION ${SHAREPATH}Data/Scripts/Multiplayer)
