Hi! I've run into the same problem with many custom commands as discussed here: http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/13434 Which is referenced in this bug report: https://cmake.org/Bug/view.php?id=15612#c38924
I've had a look at this problem because this is the only thing that blocks us from using ninja. It seems to me that there are two possible solution: * use a response file (rspfile and rspfile_content). This unfortunately is only possible when modifying ninja to support multiline response files. As far as I know this is not possible now. (the $in_newline does not work in this case) * Add a build target for each custom command, e.g. instead of E.g. instead of an output like this: ---------------- build CMakeFiles\copy_czmq_3.0.2.util: CUSTOM_COMMAND COMMAND = cmd.exe /C "cd /D C:\dev\ras_robvis\vc140_x64_ninja && "c:\Program Files (x86)\CMake\bin\cmake.exe" -E copy_if_different "C:/dev/ras_robvis/src/ext/lib_czmq/3.0.2/vc140_x64/czmq.dll" "C:/dev/ras_robvis/vc140_x64_ninja/bin/./czmq.dll" && cd /D C:\dev\ras_robvis\vc140_x64_ninja && "c:\Program Files (x86)\CMake\bin\cmake.exe" -E copy_if_different "C:/dev/ras_robvis/src/ext/lib_czmq/3.0.2/vc140_x64/czmqd.dll" "C:/dev/ras_robvis/vc140_x64_ninja/bin/./czmqd.dll"" DESC = Running utility command for copy_czmq_3.0.2 restat = 1 build copy_czmq_3.0.2: phony CMakeFiles\copy_czmq_3.0.2.util ---------------- produce an output like this: ---------------- build CMakeFiles\copy_czmq_3.0.2.util.1: CUSTOM_COMMAND COMMAND = cmd.exe /C "cd /D C:\dev\ras_robvis\vc140_x64_ninja && "c:\Program Files (x86)\CMake\bin\cmake.exe" -E copy_if_different "C:/dev/ras_robvis/src/ext/lib_czmq/3.0.2/vc140_x64/czmq.dll" "C:/dev/ras_robvis/vc140_x64_ninja/bin/./czmq.dll"" restat = 1 build CMakeFiles\copy_czmq_3.0.2.util.2: CUSTOM_COMMAND COMMAND = cmd.exe /C "cd /D C:\dev\ras_robvis\vc140_x64_ninja && "c:\Program Files (x86)\CMake\bin\cmake.exe" -E copy_if_different "C:/dev/ras_robvis/src/ext/lib_czmq/3.0.2/vc140_x64/czmqd.dll" "C:/dev/ras_robvis/vc140_x64_ninja/bin/./czmqd.dll"" restat = 1 build CMakeFiles\copy_czmq_3.0.2.util: phony | CMakeFiles\copy_czmq_3.0.2.util.1 CMakeFiles\copy_czmq_3.0.2.util.2 DESC = Running utility command for copy_czmq_3.0.2 build copy_czmq_3.0.2: phony CMakeFiles\copy_czmq_3.0.2.util ---------------- I did not yet have a look at the cmake code so I am not sure how difficult it is to implement this, or even if this is the best way to solve this. Any comments? is this reasonable? Martin -- Martin
