Created attachment 107460 [details] Patch for astro and marble CMakeLists.txt that fixes the bug I am using master branch and current commit is 81bdc81. When Marble is built under Windows and macOS in order to be used as a library, the installation is broken. The installation folder does not contain any include files, libraries, and a .pri file. The problem can be tracked down to CMakeLists.txt in src/lib/astro and src/lib/marble. See that line '# TODO: find how to install & deploy library, headers and config files as bundle for development'. Basically, under Windows and macOS no deployment is happening. However, at least with CMake 3.8.2 it is easy to fix (or work around it). One need: 1. Do not return under Windows and macOS 2. Modify installation targets and add export symbols. Attached is a patch file, which fixes the bug.
In addition to having libraries in ${CMAKE_INSTALL_PREFIX}, one can also copy them to ${CMAKE_INSTALL_LIBDIR}. Otherwise .pri file knows nothing about ${CMAKE_INSTALL_PREFIX} location and it is hard to locate the actual libraries automatically. When information about actual libraries is available through .pri file, one can automate the deployment through QMake. Otherwise a dependent application will compile and link OK, but user will need to manually copy all dynamic libraries to executable (or modify the path). So, install rules for marblewidget can be: if(WIN32) install(TARGETS marblewidget EXPORT MarbleTargets RUNTIME DESTINATION ${CMAKE_INSTALL_PREFIX} ARCHIVE DESTINATION ${CMAKE_INSTALL_LIBDIR}) install(TARGETS marblewidget RUNTIME DESTINATION ${CMAKE_INSTALL_LIBDIR}) elseif(APPLE) install(TARGETS marblewidget EXPORT MarbleTargets LIBRARY DESTINATION ${CMAKE_INSTALL_PREFIX}/Marble.app/Contents/MacOS/lib) install(TARGETS marblewidget LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}) else() install(TARGETS marblewidget EXPORT MarbleTargets LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}) endif() Another option will be to include more information in .pri file: set(PRI_DATA_DIR "${MARBLE_DATA_INSTALL_PATH}") if(NOT IS_ABSOLUTE "${PRI_DATA_DIR}") set(PRI_DATA_DIR "${CMAKE_INSTALL_PREFIX}/${PRI_DATA_DIR}") endif() set(PRI_PLUGIN_DIR "${MARBLE_PLUGIN_INSTALL_PATH}") if(NOT IS_ABSOLUTE "${PRI_PLUGIN_DIR}") set(PRI_PLUGIN_DIR "${CMAKE_INSTALL_PREFIX}/${PRI_PLUGIN_DIR}") endif() ... QT.Marble.depends = ${PRI_DEPS} QT.Marble.data = ${PRI_DATA_DIR} QT.Marble.plugins = ${PRI_PLUGIN_DIR}
