Hello, I can't say when these errors first appeared, certainly not in Boost 1.63 . I have a project working with cmake and the following cmmake lines: set(Boost_USE_MULTITHREADED ON) find_package(Boost 1.58 REQUIRED COMPONENTS program_options filesystem date_time system) if (Boost_PROGRAM_OPTIONS_FOUND) set (INCS ${INCS} ${Boost_INCLUDE_DIRS}) set (LIBS ${LIBS} ${Boost_PROGRAM_OPTIONS_LIBRARY} ${Boost_SYSTEM_LIBRARY}) endif (Boost_PROGRAM_OPTIONS_FOUND) Which says that it found the libraries and lower down produces this error: CMake Error in CMakeLists.txt: Imported target "Boost::program_options" includes non-existent path "/include" in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include: * The path was deleted, renamed, or moved to another location. * An install or uninstall procedure did not complete successfully. * The installation package was faulty and references files it does not provide. This error appears twice in the output. My cmake skills are too meagre to trace it to a particular point in the Boost Cmake modules. Could someone please help? Is it perhaps my fault for not updating a call somewhere?
