Hello, I use the cmake-command on unix and it works well, but. But Windows, it told me that: CMake Error at src/gui/CMakeLists.txt:99 (INSTALL): install Library TARGETS given no DESTINATION! The INSTLL in CmakeLists.txt is like this: INSTALL(PROGRAMS ${PROJECT_BINARY_DIR}/bin/qfrt DESTINATION bin) Why? Thanks. Kermit
