compilecommands. I am building target inside a folder and is called via addsubdirectory.The folder has its own CMakeLists.txt file. I expected to be able to use the $ generator expression as a condition in an if() but that doesn't work. I have a CMakeLists.txt in the root of my project with CMAKEEXPORTCOMPILECOMMANDS turned on. Additionally like this the target in the subproject keeps their dependency to the output-file. If you set the CMAKELIBRARYOUTPUTDIRECTORY variable in your CMakeLists.txt before calling addsubdirectory (and the subproject does not override it), libraries should fall into the right place. Im trying to write a CMakeLists.txt which copies as a post build event required dlls from external libraries to the folder in which the executable is located after building. Either IMPORTED_LOCATION_DEBUG or IMPORTED_LOCATION_RELEASE. Copy or move libs after build with cmake. This is a problem in your case because the samples folder isnt tracked as a dependency, nor are any of the files in it. They let cmake decide when to rerun cmake. In Qt5WidgetsConfig.cmake I can see it creates different properties for the Qt5::Widgets target to refer to the DLL, depending on the currently active configuration. People who use cmake, after running cmake once, expect to just be able to run 'make' or 'cmake -build. I'm trying to use add_custom_command to create a post-build command to copy Qt DLLs to the executable directory. If your target was installed after calling CMake with -DCMAKEINSTALLPREFIX/usr, then your lib would end up in /usr/lib (as expected with prefix set to /usr ), but your headers would end up in /include (probably not expected). That way CMake knows it's part of the generation of the build system, so if it changes, it will get copied again when you run the build. More importantly though, the file globbing approach isn't going to work for the first time you build your project if those DLL's are built as part of the same project, since none of the DLL's would be there when you first run CMake in such an arrangement. Run CMake with one of the following command signatures to specify the source and. Generally, you'll want to use configurefile() for what you're describing. Say your target is called MyTarget, then you can do this: add_custom_command(TARGET MyTarget PRE_BUILDĬOMMAND $ -E copy_directoryĬMake supports a shell type file copy.New to CMake, and I'm having a hard time understanding how to use generator expressions. The top-level directory in which buildsystem files and build output.
