It is present in my version of Qt3; see this page: http://packages.ubuntu.com/lucid/i386/libqt3-headers/filelist I am not sure why it does not exist on your system. If it is not a generic file present on all Qt installations then you may have to let CMake search for it and conditionally remove the reference to it based on the CMake search results. > >> Also please be aware that for all modules that rely on TQt, you will >> need >> to detect the presence of the TQt headers, and pass the "-include tqt.h" > > I created a file named TQt.pc, for detecting is via pkg-config > >> flag to gcc.
