Hello all<br><br>I want to make my target dependent on existing non source file on disk.<br>So far I have the following :<br><br>SET_SOURCE_FILES_PROPERTIES(main.cpp OBJECT_DEPENDS ${CMAKE_SOURCE_DIR}/myfile.txt)<br>ADD_EXECUTABLE(MyTarget main.cpp)<br>
<br>But the this does NOT work, if I touch myfile.txt MyTarget is not rebuild.<br><br><br>I was searching the posts and I found that this can be solved with something like this :<br><br>add_custom_command(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/dummy.cpp <br>
COMMAND echo "/* this file is empty */" > ${CMAKE_CURRENT_BINARY_DIR}/dummy.cpp <br> DEPENDS ${CMAKE_SOURCE_DIR}/myfile.txt )<br><br>add_executable(MyTarget main.cpp ${CMAKE_CURRENT_BINARY_DIR}/dummy.cpp )<br>
<br>But this solution is not the most elegant becauseit requires generating of dummy file which need to be added as input to add_executable. <br><br>Also the following works : <br><br>add_custom_command(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/dummy.cpp <br>
COMMAND echo "/* this file is empty */" > ${CMAKE_CURRENT_BINARY_DIR}/dummy.cpp <br>
DEPENDS ${CMAKE_SOURCE_DIR}/myfile.txt )<br><br>add_custom_target(CustomTarget ${CMAKE_CURRENT_BINARY_DIR}/dummy.cpp)<br><br>add_dependencies(MyTarget CustomTarget)<br><br>But again this creates new target which shows up in my Visual Studio solution.<br>
<br>So I found the first code with OBJECT_DEPENDS most acceptable. Can someone through light on this and say why it does not works? What I am doing wrong?<br><br>Thanks for the help<br><br><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 12"><meta name="Originator" content="Microsoft Word 12"><link rel="File-List" href="file:///C:%5CUsers%5CNikola%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><link rel="themeData" href="file:///C:%5CUsers%5CNikola%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_themedata.thmx"><link rel="colorSchemeMapping" href="file:///C:%5CUsers%5CNikola%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"><style>
